One more vote against self-medication. It's dangerous, and more dangerous as we get older.
There are some bad therapists but there are many, many good ones. If the first one doesn't work, try another.
I have been very close to where you are now. You just want to DO something to ease the pain. The problem is that if you head in the direction you talk about in your post, you are letting your GID control you. No.

You want to control it. It sounds easier to just let it carry you off, but in the long run you will fare better if you remain in control. Don't do anything that will take the matter out of your hands.
Seek therapy, or at least a support group. Take control of the process. It is hard, especially in the beginning, but you're more likely to end up where you want to be - happy and fulfilled.

Good luck Phoebe. And welcome to Susan's.

Many of us here know what you are going through. Be tough, girl, and get the help you need.
