Sounds like you have been dealing with this your whole life. That’s harsh. Very hard and distressing in itself. Sometime sleep is a way to put it to bed. Though I toss and turn most of the night. Meds help. Therapy or self aids help. But anxiety is a monster unto itself. Hard to control. Meditation or mindfulness can put you in a relaxed state. Slow things down. Hear your breath rate lower the tension. I’ve battled this too but not the extent you have. It’s a good sign reaching out. Express yourself so others. People you dont even know can reach out lend a hand and say we are here to help.
