loosing your rock.

me and my best friend just broke off out friendship. it was a mutual descions. she's don't a lot of things to hurt me latley and just seems blinded by her boyfriend. I'm not sure what I did to her, I've tried to be a really good friend but everything I have going on in my life, I have a tendency to call her and just want to talk about my problems, but I've been trying to listen to her. she says I use my problems (deppresion, anxiety, suicidal, PTSD, eating disorders, and a fycked family) as excuses and that I need to just stop feeling sorry for myself and get over it. idk. she was my only friend and I feel so lost. I feel like I have no one. where do I go? what do I do? has anyone gone through something like this? how do I get through it? I wanted to lay on the floor and give up 24/7 but now... I layed on the floor and didn't... couldnt move. I just don't know what to do.
