Earlier this year, it was the first time ever that I get to see a psychiatrist to give a diagnosis on my mental health. There was many complications before the doctor declared that I am Bipolar II. I still question myself if the diagnosis he made was right because the symptoms of hypomania does not perfectly match mine. I did recognize some of the symptoms like having racing thoughts before sleep, have insomnia sometimes, being impulsive, agitated or feel annoyed and also love to shop a lot. And I'm also sexually active like I always am. But my private doc said its because of hypomania? But I don't splurge until I'm broke, get into fights(although I do get angry because of reasons but keep it to myself), think myself as superior, be delusional or anything like that. I also have moments of depression for few hours, then the next I'm feeling much better or vice versa.
So my questions are,
1) How can I be sure of myself that I'm indeed Bipolar?
2) What if it's just how I am made to behave, my personality?
3) How long does hypomania lasts? Will I always be hit with depression right after hypomania?
4) Does it mean that I can either have hypomania or depression only? Will I feel normal in between those two without medication?
5) Can you still tell yourself you are hypomanic but still carry on being hyper?
6) Any definite sign to tell if you are bipolar II?

I'm sorry for asking so many question but I really need to find out as it has been bugging my mind for a very long time. I'm asking here since maybe you guys know what it is like, you guys have the experience so I need to hear them in order to really tell if I have it. I hope my words aren't all over the place that it doesn't make sense. Please let me know if I should provide more details for your info. Thanks! If you wanna find out how I was diagnosed with Bipolar II, please read my next post. It's a long one so I posted it separately. Let me know what you guys think.
