You articulated your pain just fine. I hear you. I had a rough week last week...very rough. I won't get into it, but I felt that "tunnel at the end of the tunnel" feeling many times.

All you can do sometimes is just let the time pass and keep going. If there are things you need/can do to improve your situation, try to do them as best you can. You'd be surprised how one or two little accomplishments can make things better.

Good luck.
