Tengu is right, Kasanip. You have nothing to apologize for. I'm sure everyone here has experienced feeling down and wanting things to get better. Nor is there anything wrong with showing it in a place where you can act freely. This isn't a job, school or otherwise somewhere public, everyone here is here voluntarily and this thread at least is yours.

Also, I'm sure that most people here have been depressed at times too and felt the need to talk about it, so they'll understand. So don't feel guilty for it.
