Doubts about my Bipolar Disorder diagnosis

sometimes i have doubts like “what if i’m not actually bipolar and i’m just dramatic and wanna feel special” but then i think about this one time i had this delusion where i believed i was an alien from space that was born on earth to save the human race. i thought i could predict the future and read peoples minds. i GENUINELY whole heartedly believed this for around a month. it was a lot more complex than that of course but i can’t believe i thought that bro LMAOOO😭😭 and i thought it was normal (i wasn’t diagnosed yet at that point) anyways i find it kinda funny so thought y’all would relate
