Hi and I am sorry. I agree to ask for an mri of your brain and spine. See if they can do both as they did for me at the same time to just rule out other conditions. I am assuming you are seeing a neuro but have you been to other speciaties and ruled out things like auto immune etc? Have you had extensive bloodwork done? For the depression can you see someone to help on that side? Trust me I know the cycle of pain and depression. I also understand the fears of living like this for ever but you have to hold hope to finding the right treatment and things can get better. I know that can be hard when one is in a bad spot but do you have a good support system that can help you? Hang in there
