Yay for you.
Well done - it took a lot of strength for you to get this far!
If you are sick, there is no place for embarassment, so please don't ever contemplate feeling embarassed again.
Your GP sounds like a really nice doctor.
I think going inpatient may be useful if you fall back into the deep hole. In the mean-time, I hope things work out fine for you!
Why do you have to wait until Sep to see the psychiatric unit?
Is it a state one, or is this the earliest and private practitioner is available?

I'm starting on Lamical and may add Wellbutrin therafter (one drug at a time); hoping I have a better experience than you.
