Adhd burnout or bipolar

So I do this thing where I'm so incredibly happy and social sometimes and other times i literally cant speak a sentence without stuttering and can't really even think of the words I wanna say. The annoying thing is that people have noticed and told me "wow you're so funny and silly today". Or "I've never seen you so energetic". Which maybe I'm getting in head, making me less confident to talk to people when I'm feeling less like "myself" that day. I just notice it myself that I'm so different sometimes and it makes me sad cause I wanna be the "good version" all the time. I went to a psychologist and was diagnosed/ met the criteria for both adhd and bipolar 2. The thing is I don't know if the "bipolar" is just symptoms of adhd that appear that way. I know it could be both but I guess I'm just curious if you guys experience the same thing without being bipolar and how do y'all deal with it.
