For me, i do take meds every day, even if I think I'm feeling ok. An anti-depressant should stop you from getting as triggered by friends and family, and keep you out of the depression zone.
But it's very much a personal decision.

If you want to walk this road without meds, your T is the primary 'crutch' to get you through this. You need to trust your T and she must take you serious. It takes a while to get to that stage. Initially you may only discuss things that happened in the last week, and eventually start to discover patterns and disect these further. A T is a great opportunity to really open up, as they are unbiased and bound by a confidentiality agreement.

If you need someone to chat to, feel free to PM me. I hope you are getting enough sleep and recharging your batteries.
When is the next time you see your T, and how often do you see her? Do you ever see the T privately i.e. no dad or social worker?
