Thanks everyone for your advice and replies.
I have made an appointment with my pdoc, for late April

And that's the soonest I can get it. I'm afraid about...well, how long can I handle this? Can I handle it until my next appointment? And until then, what support can I get? All I have is a pdoc, no family doc, and no therapist.
Today I kind of told my dad that I was going through a tough time, but didn't feel like I could tell him yet what exactly was bothering me. So I'm sort of making progress, I think. =/
