I'm sorry you're feeling low. I hate it when I feel like that. Can you think of something you like to do? Do you have any hobbies or play an instrument or anything like that? Would you be interested in working on some sort of "kit" as in making something from a hobby store?
I certainly hope this passes soon, and doesn't go into a full-fledged depression. Try to keep busy, get outside if you can, do something -- anything. I wish you the very best. Please keep us posted on your progress, okay? I'll keep you in my prayers. God bless & take care. Hugs, Lee
