I went looking for a diagnosis too when my depression got worse. My first pdoc said I was suffering from depression but wanted me to try to overcome it without meds. A combination of a stressful job/work environment, my father's escalating alcoholism and being dumped sent me over the edge into a manic episode that lasted a few months. That's when I got another pdoc who diagnosed me with psychotic depression. He put me on an anti-depressant and an anti-psychotic and I recovered from the mania but went into depression instead. At this point I was more lucid and had a niggling feeling that I had something more than depression. So despite objections from my current pdoc and got a second opinion. I was diagnosed as bipolar 1 after just one consultation. I'm currently switching pdocs and soon to go off the current medications and get on Depakote. My new pdoc is much more thorough and supportive. It's only been two months since I've been diagnosed so I haven't really absorbed it yet, lot of self-blame and shame still. But that's because I know that this time the diagnosis is right, I've had manic episodes since my late teens but neither I nor anyone else knew what it was. My friends have always known me as occasionally "hyper", in fact I'd never even considered bipolar disorder until I took a self test online.

What I'm trying to say is, you need to listen to yourself. The brain is an organ like any other in our body and human beings just know when something is off. So if you feel that your diagnosis is incorrect, get a second opinion. Don't withhold information from your pdoc and things will work out fine. Good luck!
