(Most, if not all) GPs aren't qualified to diagnose mental health issues... you need to insist on getting a referral to a psychiatrist.

Mine tried to give me seroquel right after I said that I probably needed to see the psychiatrist - she ignored my 1 request of not taking a med that had a huge chance of weight gain.. and I'd read somewhere that seroquel isn't recommended for people with a family history of diabetes. Plus, why on earth was she trying to give me an antipsychotic? I don't have issues with that. She was trying to give it to me because I explained just how little sleep I'd been getting since starting sertraline (zoloft). I don't think someone should prescribe an antipsychotic as a sleep aid when there is no other reason for an antipsychotic! So I flat out said no.
