Julie,
When I was first dx I dwelled upon every last symptom I had - even if it wasn't bothering me too much - I think I "felt" them more then than I do now because it was new and scary and I didn't know what was coming next.
Fast forward to today - I still am bothered by my symptoms and some days they are worse than others but I have learned to pick and choose what I want to let bother me and what I don't. It's the only "control" I have over this disease. I know you're not dx with MS so all these symptoms you're having must seem magnified simply because there is no name to put with them.
I'm not discounting your distress - just offering a suggestion to maybe relax a bit and do something to take your mind off the constant barage of symptoms you have. You said you have help come in to take the children and cleaning chores off of you sometimes - use that help to take some time for yourself and go get a cup of coffee or go to the library or to the bookstore and browse. Like cimmonz suggested - even a break from the computer to give your CNS a rest can help, too.
I hope you feel better soon.
