Chronic pain that is unbearable

I was abused heavily as a child and have chronic pain from the amount my body endured as a kid. And because I'm so young no one in the medical field listens to me. When i go to the doctor and can barely even walk in there they just send me back home or I get sent in circles going from doctor office to specialist to psychical therapy. And i have a really hard time doing a lot of it because of the trauma involved. I am unsure how to meet my needs when my pain has gotten to be constant. And as it's a constant i get flashback after flashback. I've been in what feels like a flashback nightmare since late December. Christmas i was out and couldn't even put pressure on my knees. As i layed there it felt like my knees were going to snap inward. I can't even stand to cook or even shower and i feel help less. My mental isn't doing well and my Smi clinic (severely mentally ill) clinic isn't helping me. I'm alone in this because I'm in so much pain i don't see my friends anymore because i can't even walk and i am always grunting and groaning. I miss appointments constantly. I've quit so many jobs because the pain is unbearable.
