Depression and anxiety have been the real killers for me during this process. All of the physical stuff- the sensitivity to temperature, the muscle twitching, the constant desire to be walking, yeah they're annoying but I could ABSOLUTELY cope with them without the anxiety and depression. Though don't get me wrong I know people get much worse physical symptoms than me.
It's all mental for me. I'll have a run of good days then boom a bad day. Then a good day, then a few bad. It's weird, no real pattern to it. I'd say no rhyme or reason, but of course there is a reason. It's just not a reason we yet understand.
