Welcome!!
And I agree with the above....Only a pdoc can make a diagnosis and I would advise not to put off making an appointment.

Now, about your fear that if you are bipolar and you are put on meds you won't feel that hyper happiness again...
Bear in mind that even the highs you described above can be quite destructive or might evolve into very uncomfortable and scary hyperness. Potentially followed by an equally scary depression...I don't mean to scare you, just don't take the highs lightly just because they feel good compared to the depression spells - if you do have bipolar, the sooner you get treatment for it, the better. But don't dwell on it until you see a doc

I hope it all goes well!
