Sorry about the delay in my response. I've had a really busy week.
Oh that is crap about the conflict of interest with your school counsellors. Are you on a waiting list with anyone/perhaps your counsellors could do a referral?
I understand that you may not want to tell people because it feels really vulnerable. I also struggle to even tell my psychologist sometimes for fear of being too vulnerable. it's a very difficult feeling to deal with, but it becomes easier with practice. Like, up to now, your experiences with vulnerability have not been good with your friends. But if your parents/boyfriend/doctor were to respond well, you'd develop a good 'bank' of positive experiences with being vulnerable. After all, everybody has these issues themselves...just about different things.
Ah...yeah school is really tough. People can be very immature about these things. My sister supported this girl with depression from year 10-11, and in year 11 it was every night on the phone for at least an hour. In year 12, the girl decided she didn't like my sister anymore and said she hoped they never saw each other again after school. I dunno. People can be mean for no reason and while it's hard not to take personally, I really think it's just a reflection on your friends and not you. And as you say, it's not worth trying to be different to who you are to please people who clearly have their own bubbling issues.
Have you ever thought about calling the Beyond Blue support line on 1300 22 4636? I mean, it's not the same as having a counsellor or psychologist, but when you are struggling, it can be nice to have someone (even a stranger) to speak to on the phone.
