vertigo and balance issues, I can't lift anything without feeling dizzy

(I should preface this with the fact that i had pretty bad dermatillomania for about 20 years so I was in awkward positions applying a lot of pressure to my face, twisting and my neck to do it sometimes for 10 hours a day almost every day.) December 2016 I was sitting at my computer desk in the morning probably engaging in said behavior when suddenly my legs and arms went numb and I became dizzy I thought i should probably just get up and walk around and get some circulation going and id feel better but this happened a few more times that day and i ended up going to the hospital where they told me i was having a panic attack ( I wasn't) and I was fine. Ever since that day I have had balance problems (feel like i'm walking on a boat) and dizziness with what seems like every movement I make (I can't even sit in a chair without back support or do dishes or cook myself a meal without feeling like I'm going to fall over or the room in spinning) I have been to chiropractors, osteopaths (osteo said c1 and c2 were out of whack but i feel like that would show on an mri or am i wrong?), neurologists (said there was a little bit of white matter in frontal lobe but was probably just from past migraines), psychologists, eat (found nothing), had an mri of my neck and back done (nothing was found) and I did physical therapy for neck and inner ear for a few months nothing has helped. I really think it's my neck due to the new pain and constant cracking and grinding sounds and daily headaches/dizziness with head movements I can't lift anything without feeling dizzy and now lifting even a glass of water feels like it's 40 lbs, can't stand with my hands on my hips my body just starts swaying . Does anyone have any advice or similar symptoms? It's been a year and I really want my life back! HELP :(
