It'll be OK, Bones...
You can tackle the issues, if you only deal with one thing at a time - pick one thing; do what you need to do... rest or reward yourself... then pick one more thing.
At the university, we had a "community nurse" who pointed out that the quickest way to lower stress levels, was to learn realistic expectations on how much could be accomplished in one day. Instead of a long list of things... she suggested that there was really only enough time to do 5 things. (I've since learned that 3/day is more comfortable for me... and enough for me to feel I've been "productive"; each of us has our own comfort zone here, I think.) And sometimes, there's even an "order" that things need to be done in... what I call "dominos"... I can't accomplish the real goal until I accomplish about 5 other things first - they're prerequisites, you know?
It will be all right...
