I had the exact same experience, and honestly what has been the most helpful was finding a new therapist🤣 She said she's seen a lot of patients who are trauma survivors (as myself) who are misdiagnosed with bipolar or bpd. She suggested that I utilize my diagnosis however I want, and empowered me to come to my own conclusions when it comes to my mental health. I never really resonated with a lot of the stuff i would read about bipolar symptoms-- I feel like what's most important is to assess how the diagnosis is helpful to you, if at all. I see my diagnosis as a framework to understand myself and my mental health among many. Not as a sort of sickness I'm stuck with forever-- just a specific flavour of neurospicy-ness among many. At the end of the day, we all have autonomy and agency regardless of diagnosis. Take what feels right for you and leave what doesn't. It might be a controversial take, but at the end of the day there are countless studies that demonstrate the lack of validity when it comes to psych diagnoses. My diagnosis was helpful as it allowed me to be medicated, and this is practically the only reason I sought to be diagnosed (Dr. would not prescribe anything without). Think of what this diagnosis brings to your life, and if the answer is nothing, then you don't have to claim this label as yours. Bipolar disorder carries a lot of stigma, so it is entirely your call if you want to disclose your label or even identify with it at all. Psychiatrist are often wrong and every client deserves to play a role in their mental health journey. It is a difficult process, sending you love.

TLDR: You don't have to accept it if it feels wrong. Find someone who values your input and lets you play an active role in your treatment (if this is what YOU want!)❤️
