Hi! So I'm meant to be starting DBT this week (on Thursday). I was very excited and looking forward to it as I've been waiting to get in since the start of this year and it's finally in place. But I had to go get evaluated by one of their psychiatrists and it somehow went weird (because nothing can go right in my life lmao) basically he asked me if I self injure because it was in the notes from an old psychiatrist I used to see. I said yes but I wish I said no now lol. Anyway so then he gets my mum in at the end (I'm 18 by the way) and he just BLURTS OUT that I self harm which got me in deep shit with my mum. (He doesn't even know me at all this was the first time I had ever met him and it really pissed me off cos he doesn't know what my home life is like and it made things sooo much worse for me) and then he starts saying I need to be on medication. 
Anyway so I was really pissed off and I asked the lady who runs the DBT if I can have a different psychiatrist etc etc. and she WAS GOING TO CANCEL MY SPOT because she said I should be on medication and I was like umm I had to email sooo many people to change my uni timetable so I could be free to come to this therapy don't cancel my spot!!! 
She also said DBT is an open book and I can't keep secrets (referring to the whole self harm issue) 
I'm a bit scared now because like I can't have my mum knowing about self harm it just makes things at home really bad and makes me feel soooo shit when she's yelling at me over it. Do you think the DBT people would tell her again? 
Also in general what is DBT like? What should I expect? Any advice or anything?
