Does this look like bipolar? How often do depressive episodes usually last for you?

I’ve struggled for the last 14 years or so (mental health struggles started when I was 12) and I always thought I just had regular depression. I’ve felt depressed for as long as I can remember but there was times where I feel better, and I start feeling like myself. This is usually very short lived, like less than a week periods where I feel unusually motivated and optimistic about the future, it’s easier to do stuff and actually be productive, and I also need less sleep. I’ve been reading more about bipolar 2 and I think that is called hypomania. I want to bring this up to my doctor but not sure how. I’m so exhausted. Ever since I was in high school I explained to my friends that my moods feel like a roller coaster. My life feels like I’m constantly struggling and surviving. If you’re on mood stabilizers, please tell me your experience and how they have helped you. I need hope to hold onto right now.
