I cant walk...

I'm 21 F and undiagnosed but I have a lot of the "textbook" signs of MS, the worst of which being that my legs aren't working right. It started with foot pain (shooting pains like I'm being electrified) and within four days the shocks had spread to going up my legs to my mid thighs. My legs are Jell-O, my knees either buckle or go backwards. It all happened while I was getting over mono. I went to the ER bc I don't have insurance and it scared me. They did blood work and a CT and told me I was stressed. I'm on cymbalta and lyrica and it's been a month of being in a wheelchair or crawling around bc the wheelchair doesn't fit in my apartment so I'm pretty sure it isn't psychosomatic. I don't want a diagnosis from y'all bc I know you aren't doctors and even if you are you don't have access to my full medical history and all that jazz. I guess I'm looking for support, I'm so frustrated... I can't sleep, I can't breathe bc my ribs feel too small for my lungs. I can't cook anything or clean. Its hard and I feel so bad for my husband. I feel so guilty for putting everybody through this. I'm sorry if this isn't allowed bc I'm not diagnosed I'll take it down if I need to. Thank you for reading if you did, sending love to you all
