Hurt about not being invited to the wedding shower, should i say anything?

So I have a friend who is getting married this year in August and I just found out she had a bridal shower today and I wasn't invited. I'm very hurt. Its piling on to the fact that I'm starting to feel like she wants nothing to do with me anymore. I know shes busy planning the wedding and getting everything ready plus shes a teacher and plans the prom so she's had everything happening all at once, so i've tried to give her space and not bother her too much. It all started back in January, we got together after she had gotten engaged over the holidays and I told her that I would love to help her out in anyway that I could and that just to let me know. She had told me she would let me know when she was going to have a bridal shower or engagement party or bachelorette trip and keep me in the loop, I said that sounded great. She texted me in February telling me that they were planning her bachelorette party for July in SC and asked if I wanted to go. I told her I would love to, to just keep me updated so I know the days and how much my part will be and if we're flying/driving, etc. All the things somebody would need to know so they could plan their schedules, figure out costs, etc accordingly. I was unemployed, so she knew that I had to plan everything ahead to make sure I would be able to cover all my bills and costs until I could get another job. She texted me back telling me the days and that we were driving but said nothing else. Well, I waited cause I knew she was busy but I planned my schedule around those days and figured I would hear something from her soon. She then texts me in March asking for my address, since i had moved recently and then mailed me a wedding invite. Since then she has had 3 engagement parties and I wasn't invited to a single one. I was hurt but I let it go deciding that maybe it was small family gatherings and they only invited a small group of people. Then I get a text from one of her bridesmaids at the beginning of June, who I don't know, who the only way she could of gotten my number was to get it from my friend, asking me for $100 for my part of the hotel room for the bacherlorette trip and put towards my friend's part of the bacherlorette trip so she wouldn't have to pay for anything and gave me her info to wire it to her right then. I'm getting pretty upset and hurt now. My friend hasn't bothered to respond to anything I've sent or said to her and I directly asked her to keep me informed. I had to ask this bridesmaid what the days where, the times we'd be leaving/coming back, where we would be staying, how we would be getting there, what we would be doing. You know things you sortta need to know to be able to go somewhere and be able to plan how much money you might need. She really couldn't tell me much other than the days, didn't know the time, knew we were driving but didn't know if everybody was carpooling or driving separately, and didn't know what we would be doing there either. So I gave her the money, asked her to also please keep me informed in hopes that I don't feel like i've just given money to somebody and I'm not even going to be informed so I can actually go on this trip. Now it's been a few weeks since that text from the bridesmaid, I haven't heard a word from my friend or the bridesmaid and we're supposedly supposed to leave in 3 weeks. Plus I noticed that my friend had finally completed her wedding registry so I figured she was going to be having a bridal shower soon, so I go to message her today in hopes she'll not be too busy and I look online before I do, only to find out that her bridal shower was today. I can't say it was just immediate family/friends cause there were quite a few people there. I'm extremely hurt. When I get hurt like this I tend to not thing clearly and I tend to lash out. I'm trying to stay calm and do this the right way. I feel like I need to say something. What do I say? Am I being stupid and she really no longer cares to be my friend? Should I even be going on this bacherlorette trip? Could I even get my money back if I backed out now? What do y'all think? Am I just overreacting?
