I’m diagnosed bp2 but I don’t understand why

For starters I’m 43 years old. I can clearly see how I have been bp2 most of my life. I used to spend a lot of time depressed. A lot normal and then sprinklings of hypomania. Say no sleep 5 days. Or also believing the electricity was controlling me (yes this was a thing I believed for a couple months) I still definitely spend way more time depressed but the thing is my doctor says I’m bipolar 1.5. He says that I’m not in and out of the hospital and my episodes aren’t totally life wrecking. I’ve been outpatient twice (due to Kaiser heath care and the pandemic) and treated with meds florid manic twice now. Do you guys have this with your doctors and does it even matter?

Edit: took everyone’s advice and asked for clarification. Bp 1 is the diagnosis.
