You need better doctors . I hope the “ brit” in your profile name doesn’t mean Britain . Their “ free” medicine is notorious for never getting to the bottom of any complex medical condition

Sounds like you grew up near a toxic chemical or nuclear dump.. Sometimes when people are sick all the time it stems from early life development in a toxic environment..

I'm so sorry you are dealing with all of that. If you feel the need to vent you can pm me. I promise not to yell.

Just vent, it’s good to vent, if people shout so what! I did date a girl who had similar issues and it was really hard to understand. She’s gone on to do really well and be successful and I kinda regret splitting up with her.

You need to fight to find out why you have all of these symptoms.
Strength is sometimes physical but the most important kind of strength is mental and come from within.
And no matter who you are at some point you have to just do your best and stop caring what others think about you.
