I'm sorry you're passing through rough time
Well, it does sounds strange that your familly do these kinds of things but, does your familly know about your situation? Your depression and all that.
It is perfectly normal that many people don't understand what depression is, or either, some even can't see the difference.

But how do you plan to find a job there? I mean, are you trying to stay there for a while?

I'm sorry i can't be much help for now, but i still have a few questions like.
Are you older than your sister?
How long have you been feeling that way? And also, what kind of job are you looking for?
I hope you get better, best of wishes
