I feel like im losing myself

Hi im new here and I just really need to get things off my chest. I moved in with my friend because shes going through alot of medical issues and needs help which I don't mind helping but sometimes it is alot. I work 55 hour weeks overnight and don't really get much sleep during the day. My boyfriend feels like I don't care because he doesn't feel like im.puttimg enough effort into the relationship and he doesn't like my friend saying shes manipulative. My friend doesn't like my boyfriend saying he's manipulative and I really care about her but it feels like im constantly doing things she needs and reassuring her and if I do or say something she doesn't agree with she tells my mom. I love that shes close with my mom but I hate how she tells her everything I do or say I feel like I can't talk anymore and my mom's mad at my boyfriend because my friend only tells her things he's done wrong. It just feels like im being pulled in a different direction by everyone amd if I try to pull back they get mad and blame someone else but its all taken out on me. I don't even know who I am anymore outside of just trying to be the person everyone needs me to be and they always say alim doing to much yet they always point out how im not doing enough. Anyways thanks for reading this i just needed to vent about it ***.
