Does mental overload lead to worsening of MS symptoms such as pain and difficulty walking, and if so, what causes this to happen?

I've noticed that if I am getting mentally drained (even talking with someone for a length of time, say an hour...or that particular person is talking a mile a minute, I get emotionally drained) in which afterward my MS symptoms are off the charts! The ability to walk normally, the pain level is super high, I can't think, my emotions are all over the place (I even cry). I can't be the only one going through this. The more my brain is overloaded the worse I am. This could take as little as 40 mins to 2 hours and then I'm DONE!
