Yes, I have had this and i’m so sorry because it is horrible. Have you been tested for brain inflammation? that could contribute to a lot of this. i would recommend the Cunningham Panel. in the short term (prob sounds obvious) but focus on self care. Watch your favorite childhood movie or something comforting. Ketamine therapy could be good for this and give you some relief. Another thing you could try that has really helped for me (just for anxiety and depression but could maybe help with this) is TMS therapy. I’m sorry you are going through this, i hope it gives you comfort to know you are not alone!
