My auntie and cousin has ruined my family life.

I made a post online about feeling distant and they wrote to me with horrible texts saying i wasnt part of their family as i clairifed in private mail that my dad hit me,punched me and threw chairs at me during really bad arguments and how he told me it was my fault that i was bullied. He accused me many times of doing drugs and smoling which at the time i wasnt. This was in april.

Then i posted on sunday in a suicide prevention group about my expirence with depression and how i partied eached weekend , drank loads, started smoking and did some stuff with guys that i regret. Only i didnt realise this was public - i though the group was private. My nan read it and i then wrote a status to apologise and said that things were all good now and that i was only sharing the story to say its worth sticking around and not worth commiting suicide. Eberyhing was fine my other nan said put oast into past and we'll have fun at my other cousins party.

Well...my auntie in family chat with me and all of my family in twisted what i have said. She said i publicly wrote that my dad abused me (only through pm to her) , then my cousin wrotw that i admitted to doing drugs (never touchdd the stuff & turned weed down when i was offered it) and then said that my drinking and depression was because of my "hard home life" which ive never said that was the reason. It never was...She sent that yesterday after us having the conversations since April
My auntie made it out that ive been saying horrible stuff since april when my mums dad past away but didnt want to tell my parents as they were grieving. My dad obviously got angry for them not telling him.
I wrote a text to my mum with the truth and have said that they twisted everything but shes not replied and had a phone call from my nan to say my mum is really upset and that i am unpleasnt for writing those things. She also said "i thought it was just your mum you dont get on with not your dad". I dont speak to my mum often because if we talk over facbook she just thumbs up everything or ignores what me and my fiance are going through, on the phone it always seems like shes in a hurry to get off the phone and yet when i go to put the phone down she gets funny.
My prents have been to my house twice since ive been living here since march 2017. One visit was 6 months after i moved because they didnt feel welcome although they ignored every time i asked them to come over and because of the lnife situation which had already been resolved and were laughing and joking eoth me and my fiance a few weeks after at my birthday meal - i invited them up on my birthday said yes then suddenly went home as they had to fix my nans tv even though my nan was at the meal too...
The second time they came over was in september 2017 for cake as to celebrate my engagement.
It has recently took my mum 3 -4 weeks to message me after i had enough of being the inly one to make an effort to talk with her.
I dont speak to my dad. We have never been close and we find it hard to talk to each other.
They are both uninterested that i am getting engaged and slams their eyes,scowl at me or rut at me when i mention some wedding planning stuff.
None of my family cared for me being engaged
My auntie and cousin has hated me and my fiance. Me since i was a kid where my cousin would do everything to get me in trouble and Almost spilt my parents up because my dad took her side and not mine.
Then because a knife was planted in my work bag for a laugh by my uncle and i freaked as i nearly pulled it out in front of a cashier whilst i was on my way to work - i work with babies and my fiance defend me saying i had every right to be upset or scared as i could have gone to prison. All of My family told me i was being pathetic and my feelings were not valid.
Then i recieved horrible messages from my cousin about my fiance and the fact he suffers with depression where he has to take a tablet ever day to keep his seretonin levels stable.
I havent spoke to my cousin since march 2017 and my other nan said that she wouldnt come to my wedding if i did not invite my auntie or cousin. Well tough they arent and said that i was being horrible for not talking to them but honstly why i should i ?
They have vowed to ruin my life woth every chance they had and now they have offically done it. They have taken my family away from me and i cant do anything to fix it.
And to be honest i dont want anything to do with any of them and its breaking my heart every day.
