Can you go and talkto your primary care physician? This isn't a a good feeling and you shouldn't have to deal with this - "like I wish I could go to sleep and never wake up."

Have you tried journaling or getting your feelings out on paper?

I'm sorry to hear your daughter isn't local. I live far away from my family (well, not that far), but I do know that it is difficult for my parents that I'm not near by. At least you have something to look forward to....seeing her. Hang in there.
