Sorry to hear that things are so difficult in your life and your P seems not to make it any easier, but I believe she does it to push you and motivate you to get stronger. I know 6 months souns like a lot of time. I don't know how I would feel if my T suddenly told me that I won't be able to see him for the next 6 months. That would be just horrible. It's sort of beyond my imagination right now.
But then maybe there is a chance that she could review it earlier if she sees that you've done so much hard work?
I believe she is right when she means that you should be taking your medication, and I've read that when you take antidepressants you can't drink alcohol at all. I believe she needs to push you to make some changes and it's very important for you and her. What do you think?
