Anyone here with MS?

I'm in the process of seeing a MS neurologist. I've been noticing my strength is lacking in such a way that it kind of scares me. I'm tired all the time and I'm feeling really depressed about what is happening with my body. Muscle pain and nerve pain everywhere all the time. Trying to workout to just keep moving is hard when I'm not able to lift or do cardio like I'm used to and like I know I'm capable of.

If anyone here has MS or has the chronic pain can you please give me some advice on how you workout when you can't do what you know you should be able to do? How do you combat the depression?
