I can't take much more.. maybe being bullied by my friends

I feel like I have nothing left, like everything is my fault but I don't know if it is or not or how to fix any of it. I'm making myself sick thinking of everything I feel sick in the mornings and don't want to go to school when I'm at school I end up going to the bathroom to cry or go to the counselor to get out of class it all started back in November when my cousin who I have grew up with and who has been my best friend forever told my mom something about our friend that she shouldn't have and could have got the girl in trouble so me and our other friend and the girl she told it about got mad at her and then my cousin texted me and was like this is why I don't tell you stuff forget you all I will make new friends screw you all then she was like you want to know who is your true friends we all went to the mall without you one day and I said maybe we should invite you but they were like no and we were mad at my cousin and so when my cousin texted me something about the other girl I screenshotted and texted it to them I know it was wrong to do that but it was out of anger and I had completely forgot about sending the message and instead of my cousin coming to me and telling me she knew about it they would tell each other what to text me and send it to me to see what I would say like one would be like "what are the hoes doing today they seem so annoying" and I never said they were hoes or anything I just said they are still annoying me and yeah they are because they were annoying at that point I was hurt because they were ignoring me and I asked my cousin if we was all okay because I could tell something was wrong but she didn't tell me and they continued to do what they were doing and I asked if they were all good because I saw them texting and she lied about it and then my other friend would set me up to say stuff like she would be like they would still be friends if your cousin could keep her mouth shut and wouldn't tell your mom everything and I said yeah I know because she does tell my mom but and I would text my cousin and be like the hoes are ignoring me again but I never once meant hoe like for real and they should know that we all call each other that all the time and they had a "meeting" at my friends and invited me over to hangout for a little bit and then my cousin showed up with the girl she talked about to my mom when they wasn't supposed to be talking to and told me about how they knew about it all and things need to change then dropped me off at my house and said they had to work and all this then went and hung out and posted about it then the girl who my cousin told on we got mad at because she said stuff about my other friend and then lied about me and said I invited myself to go shopping with her and copied her with her clothes and tried to get our friend mad at me but when really she invited me and was like we should get matching clothes and told me to text our friend that we forgot about her that's why we didn't invite her and when I was freaking out about it she wouldn't help me with what to say and told our friend she had no idea why I said that and here the other day they all went and hung out without me and blocked me and lied about it because my cousin was supposed to come over so I asked if she was and she said she was cleaning and someone asked why I wasn't with them and I said I didn't know about it and all I did was text and ask about it and then my cousin was like "why does it actually matter what I'm doing and who told you" and was gonna block me if I didn't tell her who told and was like I'm done with you and all of this and then my friend at school was talking to the other girl loud and was like why is it any of her business and kept giving me looks and then they tried to turn the person who told me against me telling them how I snuck out one time and I lie and I think I'm better than everyone and I talk crap about people and I snuck out one time but that has nothing to do with everything and it was a mistake that happened two years ago and they still bring it up and I don't think I'm better than anyone I have a lot of problems I used to think a lot of my friends because how they can talk to people so easy and they said I tell guys I like them just for the attention which isn't even true I can't even tell my friends when I like a guy without them calling me a hoe which they have no reason to call me one I've liked maybe 3 guys in two years only talked to two of them also but didn't date them well maybe dated one but that's all ever and when I was kinda dating that one guy they called me easy and said I would sleep with him which I have never done and they said if i didn't sleep with him he would rape me and they would stop being my friend if I slept with him or he would force me they also said if I don't stop talking to him they will stop being my friend so I stopped which I regret now
