Tired of being tired. Help!

I just gotta day ive been stressed to the max lately and I just dont know what more I can take. I went through a divorce, got pregnant by a monster that threatened to kill me and said child, almost lost both of our lives at 6 months pregnant due to a bad car accident. Not to mention that bad toxic relationships in between all this. I now live with 3 kids at my grandparents and while I do help out abd contribute and have a boyfriend sometimes the way everyone acts and treats me its like nobody even wants me around or at the very least that nobody appreciates me. My 2 older kids are about to hit the teens soon so of course they are moody and the little one mentioned above recently turned 1. I cant work because i dont have a babysitter. Its just so much. I Want to feel loved, appreciated, thought about. I get nothing. My own boyfriend doesnt ever want to go out, never just stops and gets me something or sends me a sweet text to let me know hes thinking of me (i dont care about money I just want to know he cares considering i only see him on his days off and he barely touches me other than when we're in bed). Then i have talks with everyone and everyone says i take them the wrong way. I do have anxiety and ptsd so how the hell do i know the difference? Am I a psycho or are my feelings legitimate? I honestly dont know anymore but i really needed to vent.
