I’ve never felt pain like this.

My boyfriend of 3 years left me while I’m going through being sick with multiple life threatening chronic autoimmune diseases, finding out I was molested at 6, and miscarrying our child. We always hang out on Fridays through the weekend. I texted him twice four hours apart about what the plans were. I figured he was busy at work. So I got ready and packed and as soon as I was about to leave he texted me saying he had gotten off hours ago which has never happened in the three years we were together and took a nap and he was going to a party and he would come over Saturday. He didn’t tell me and he knew the whole time and he didn’t invite me when I invite him anywhere with me. I was hurt. He didn’t text me for four more hours at the party. I find out a girl that has said horrible things about me to him and has lied about horrible things and he knows not to talk to her because it’s disrespectful and if someone said something bad about him to me I wouldn’t ever look their way again and she was at the party. He never said anything. When I called him out and said how hurt I was and he was a liar he said I was crazy and dumped me and hasn’t talked to me since. I’m still going through the miscarriage and being disabled at 27 and I feel he doesn’t care. I can’t sleep I can’t eat I cry all the time. I’ve never felt pain like this and I don’t know how to get it to stop. I love him with every bone in my body. Why did he do this? I feel worthless and a burden for being disabled and probably never will be able to carry children which I have dreamed of forever. I can feel the pain in every part of my body. I can’t take it.
