Okay i know i may should ask this question long time ago when it started to me but it actually didn`t come to my mind until now...

But is it possible that someone may get depression because an action`s someone else do ?

yeah it's possible...
but doesn't that mean that persone is special to you?

Special to me ? will yeah in bad way ofc , he may be the reason for that >>2

Yes, that is very possible. Hypothetically, if someone's friend commits suicide, then everyone holding that person will be sad. Some will become depressed. That's just an example.

>>4 Thanks for the example , getting better from depression will be hard road for me because of someone made me sick...
