bottom of depression

What am I gonna do? I had dreams about him this morning. 3 stories. all about him. I woke up with heart beating. and went to bottom of depression river. Help! Help! I cried in the bus, I don't care. I was late for work an hour. It was really unprofessional.
I am such a inmature person! I cannot do any things right. Even a one simple thing. What is wrong with me. And not FUN!
Very kind friend of mine came over to san francisco to have dinner with me. How nice! After dinner I could feel better about myself again. I should go to bed. Night time is not good time to be depressed.
