My old comforting friend, pain

I've been in pain for 8+ years. Sometimes crippling and expletive causing, sometimes annoying and exhausting, but it's always always there. "If I'm awake I'm in pain" is something I told a friend early on and remains true.
Several months ago (8ish?) I developed all of these new symptoms of weakness, numbness, skin discoloration, severe cognitive impairment, skin crawling itchiness causing deep bruising and on and on and on.
Out of all of these symptoms I'd have to say the weakness and fatigue are by far the worst and hardest to fight through.

On days when I feel numb, or utterly disabilingly exhausted, or can't string a sentence together or read words, I feel so awful and generally out of sorts I just need to lie down and check out so my brain can reset or chill or whatever it needs to do in there. I get anxious in these times because if my brain isn't working right then I don't like to be away from home or away from M. He's my safety net. The symptoms come on so suddenly that I get scared to be away from home alone with my kids and have them hit. These are the really bad days.

So, on days where I don't have any of these symptoms, but only pain, it's actually and oddly comforting. Like an old blanket or sweatshirt. I've been living with it so long it truly is my

norm, so when I have "just that" it's as if I feel "normal". Even if it's severe and I can't move. I feel like my brain is saying "oh I know this. Ok I know how to deal with this".  Don't get me wrong it's awful at times still but I get it, I know how to make it better generally- though I may not always like the solution. It's just "back to normal" in my world.
 Weird huh?
