@Kyle1 it can be pretty heavy to get a new diagnosis like that, especially if you've just gotten used to what you already knew. Sounds like it's still unconfirmed, so you can probably take the time you need to process and explore before you go seeking any sort of confirmation. Do you know much about bipolar? We've got some info here if you wanted to read.
In my experience getting a new diagnosis is often a process of gaining insight into yourself and even understanding yourself better in some ways, as well as getting better treatment. The tricky part is not over-identifying with the diagnosis/label and remembering that everyone experiences their MH differently, regardless of having the same diagnosis. Diagnosis is just a guideline for treatment, not something prescriptive that determines who we are or what we value.
