People I have read your post clearly and I decided to stop searching and just stay in my job now
Do you like your job? If you enjoy your job (or as much as is possible), I see no reason to keep searching. Perhaps you can relax a little bit.
when the day comes I hope soon I will be so happy but am still depressed why?
Discover what you are meant to do. Everyone has talents, so uncover them. Find out what you really love to do.
May I just quote someone (I can't remember who's signature I read this from or I would acknowledge him/her):
"Depression is merely anger without aggression"

I think it's partly true; it's alright to get mad about something, but don't stay that way. Let your anger out, or else it will bottle up inside you. Then you won't wake up with a feeling of not knowing your meaning.
I need some love or is it normal?Or am I just plain desperate or stupid?
This is by
no means unnormal. Millions of people struggle with depression, and, amazingly, it seems to be especially worse for people who are well-off. Be patient, and eventually you'll find the right person. Don't push it, or you'll end up crashing to the ground. Relax, and don't feel bad about yourself.
