Hi Astrid, sorry you are having some anxiety about medicine. It is hard to hear what your t said. It is standard practice for a pdoc to prescribe a medicine based on their technical knowledge of how the drug works.

Trying it is the only way to find out. If you are having a tough time then it is a calculated risk that will at least give them some feedback. Ask the pdoc if you can try a very small amount and build up (use a pill cutter if possible) - this will give you a smaller more gradual change. If things are getting out of control then you can ask the pdoc to change.

A friend did seroquel and it did nothing for them. Our own preferences are often not based on technical knowledge available to a pdoc.

here is some useful info about drug prescriptions and dealing with your pdoc.
