Re: how to talk 2 ur folks
I think the first step is to find a time when you can talk with them about how you've been feeling in general, to share with them that you've been unhappy and depressed, maybe tell them why and for how long.
If that convo goes well, if they respond to this info with the concern that it sounds like they should, then they'll most likely ask if you want to see a doctor. If not, then you can ask.
But, be prepared to talk openly about yourself and the way you've been feeling, give them the info they need to make the right judgement.
