Yup, they can be good because until we know what's going on, we lack insight. The very thing we need to deal with our problems appropriately. You could try to look at your dx as a gain of power and knowledge. Both those things are needed for you take take control back.

I know it's kind of a double edged sword and there is a bit of a grieving process involved, it's important to work through that stage. There was a thread awhile back about that very topic. Bipolar will be what you make it, in terms of a label, just like anything else. We do have the power to choose what it means to us. Of course it's no bed of roses, but what in life is. We are all handed something.

Sometimes I think pdocs like to play on the side of caution when it comes to dx'ing. There has been much talk about wether it's being over diagnosed. And sometimes the symptoms are nothing short of perplexing if you do not present classically. And who with Bipolar really does? I think it could be a good thing that your pdoc is being careful about dx'ing too quickly. It's better to make sure it's the right dx than to be given the wrong one.
