Jealousy? Or... am i going crazy? i feel like i have lost my family over my happiness.

Hi ladies, I have a story to tell. It has caused me a lot of anxiety and pain around my wedding coming up in 6 months. I have to start from the beginning but maybe knowing I'm not alone can help a little.
I have 2 sisters and a mother whom have been my support system my entire life. I was in a horrible abusive relationship for 10 years and I got myself out of it, picked myself up and during the process I met a man who showed me the true beauty of life and makes me feel like the most beautiful woman in the world. He is AMAZING. Well we finally get engaged February of this year, our wedding is in 6 months. Shortly after, my older sister called me and started to question me getting married. Offered advice on how horrible divorce is (she is previously divorced) and all that is negative. It made me have to justify my love for my fiance and after the call I felt broken. Also, manipulated into thinking I even needed to justify this beautiful new chapter in my life that blossomed out of something I endure terribly for 10 years, all of which my sisters and mom witnessed. My other sister, sent me a congratulations text. And after about the 10th time seeing her in person I decided I would show her my ring. She never asked to see it. Never spoke about the engagement experience that she wasn't there for. No talk about anything. My mom, forgot I was engaged and I had to REMIND her! He proposed to me in a cabin on vacation so it wasn't family around but when we got back it was nothing but... crickets. In casual conversation with my older sister (the one who called me telling me about how awful divorce is 1 week after I got engaged) starts to tell me about how much she hates weddings. Like they are "dreadful" "how can one justify spending so much money on one stupid day" "weddings are overrated" "they make me feel so uncomfortable" (I seriously cannot make this up) another unwarranted conversation struck up about how she thinks brides are ungrateful and she hates that she has to spend money on a new dress and shoes just to attend a wedding and no gift that she could Give to the newlyweds would ever be "appreciated" ... at this point.... my jaw is dropped. I am politely nodding and trying to understand her feelings all while in my head thinking "I CANNOT ask my sister to be apart of my wedding this is going to be a disaster) but at the same time my other sister hasn't shown much enthusiasm around the idea of me being engaged and wedding planning, I don't judge people on their reactions I still wanted her to be apart of my day.... but how do you ask 1 sister over another? Long story short. I bite the bullet, I plan brunch and bring gifts and against my own gut, I asked them both to be my bridesmaids. I didn't want to hurt anyone's feelings. Next comes another conversation when saying hi to my older sister and asking her plans for the weekend what was she up to type thing... she hesitantly says "we are going to go try on bridesmaids dresses this weekend" and I was taken wayyy back because I didn't know my sisters had planned this and why wouldn't they tell me? So I said in excitement OMG that's awesome where are you going? What time? I'd LOVE to be there with you for this because it means so much to me! And she gave me little detail.... anyways, I text and call both of them that following weekend asking what they were up to. No answer. Later, I called again, and my sister answers the phone and says they bought dresses.... my heart dropped to the floor... I held back the swelling in my throat because I sincerely wanted to be apart of that moment.... so I acted happy and asked if they could send me pictures. Later that night I finally got some pictures and they chose dresses that were not in my wedding colors... I got upset, I called my bestfriend who is my MOH and who has a group text with my sisters asking her if she knew about this? And she said no.... they never told her anything about going shopping for dresses. She sends them a text and says hey ladies can I see the dresses you picked? They send the pics to her and she asked why they chose the colors they did, and 1 of my sisters says "I wasn't spending money on something I didn't like" (my colors are dusty blue, sage green, navy blue & ivory) my colors are nothing crazy and they chose to buy a red wine color..... I slept on it. After a few days I started to look up David's bridal and I found the exact dresses they chose and I saw that they were offered in my exact colors. I called the store and asked if it would be any issue if someone were to change the color of their dress (just so I could see if it would inconvenience my sisters) the store said absolutely no problem, all they would need to do is call us and change their color dress and that's it. So I texted my sisters and sent them pictures of their exact dress and asked what they thought about changing the colors and that I had already confirmed that it wouldn't be any added cost or issue with the store that all they had to do was call.... my sister withdrew herself as a bridesmaid after saying nasty things to me and said my wedding stressed her out and she could no longer be apart of this "facade" my other sister called my bestfriend (MOH) a Bit$h and she can go to hell because My friend said to them that they should have talked to me first about it. I'm getting anxiety typing this because now I feel that I have lost my sisters and my mom because she doesn't talk to me. She ignores my calls and my texts. I sent my mom a message telling her.. I am your daughter too and having your support is so important to me and that I loved her. And I never got a response. Now I am down to just my MOH my bestfriend who has stuck by me this whole time. I don't know how to read my family. I have had nothing but negative vibes and just straight coldness from my sisters and my mom. They know my pain and my struggle in my past relationship and when I finally find happiness and stability and true love.... they treat me like I did something horrible. It is so painful. I feel I am grieving the loss of my sisters and my mom because I don't know how else you move past this. This happened 3 months ago. Plenty of time has passed for everyone to think about what happened. And so far, I have not gotten any offering to meet up, talk things out. Nothing.
