How can you help someone whose depressed
You try to get them to get help for themselves
And leaving people alone while they are depressed is not the smartest thing to do... (and people who are depressed are not using time alone to relax). People who are depressed tend to stop socializing, this makes them more depressed... So try and socialize with them, but again, you cant fix this... they may need professional help...
you leave them alone.
let them relax. but if it gets out of hand like they want to kill them selves talk to them about there problems and be comforting.
but dont be to nosy were they would push you away
You should try talking to them and if it gets out of hand like there cutting,talking about goodbyes, in to drugs, or there into the depressed state for over 2 weeks then find professional help like there family
