What are the signs of depressions ??

sleeping a lot, likes to be alone, not going to public places, not meeting new people ???

Go to Iraq

I went through this not long ago and my doctor put me on mild anti-depressants which helped temporarily. I also felt very out of place and paranoid when in public and i would cry at the drop of a hat. Go to www.netdoctor.com (or co.uk) and diagnose yourself, you can type in your symptoms and theyll give you a diagnosis. Hope you feel better soon

that may be beginning of depression, sounds like something happened that wasnt cool to him, get him to talk ( if you can, dont push,well, push a little) before it hits a big depression...
depression sucks..its a very serious thing, ive been battling it for 20 yrs...if i could have just had someone to talk/listen to me, it would have done wonders...still today, a caring ear is better then meds sometimes

* Feelings of helplessness and hopelessness
* Loss of interest in dailly activities
* Appetite or weight changes
* Sleep changes
* Loss of energy
* Self-loathing
* Concentration problems
* Irritability
* Aches and pains
and finally if someone pick up all of those things then thinks about " Thoughts of Death or Suicide " ...

lack of appetite, listless and lethargic.

pretty much. this might help.
