I personally do not feature the funbag that is bipolar disorder, but what I feel like contributing right now is this:
Thank you for addressing the issue, thank you for doing something about it.
An alcoholic that doesn't even attempt to handle his/her problem of choice makes the world a shitty place for everyone involved.
A bipolar person can have very similar effects on his/her own life, his/her most beloved and just about everyone in a random manner. A bipolar disorder that isn't treated is like walking around with a nuke that might randomly go off - again and again and again, with random, mostly very negative effects.
The manic days and nights might be used for something productive, but they tend to mess people up, as reason and sanity become just concepts that do not matter or plain don't apply. Being manic might scare off people, or it might make you hard to put up with, as your reality might become something completely different to what everybody else consents as being within acceptable range. Getting a grip on that bit, wanting to stay in control should make any individual life more fun and just plain more realistically viable. I've seen people pull themselves together during university, only to completely lose it after they've achieved their summa cum laude. Anything bad you can imagine, people are capable of doing, especially when mentally ill. Boyfriend left you? Get revenge by abducting his mother and giving her HIV! Teacher gave you a bad grade? Go break into his house, strip naked and slaughter a goat in his basement! ...some things sound 'funny' when wrapped up anecdotally, but they are usually absolutely not funny at all.
If the diagnosis of Type II holds up, your manic phases are 'just' hypomanic, meaning they are not as bad as they could be. Thing is, until you and your therapist know for sure what's going on, don't take any of it lightly, as even 'mild' mania can mess you up and disturb people well into shell-shocked territory. These days, AFAIK "Type II" mainly only means that you've never had an episode of full-on mania. As these things go, the really bad ones are bound to pop up when you least need them, such in times of heightened stress/anger/fear/emotional imbalance. Knowing that, or at least discussing it thoroughly with your healthcare professional of choice, you can - beyond medication - prepare. Remember the silly instructions we all get before the plane takes off? You need some of that for situations that might otherwise send you off on a trip to loopy land.
Then there's the flip side, the other bad side of things, that is just as bound to cripple you, make you no fun at all and put you in a shitty dark place - the depression. That one is a killer all by itself, and some people might have what is called 'mild' depressions, but if you find yourself sitting in the drawer of bipolar disorder already, I think it's really just common sense to do yourself a favour and get the best medication and therapy you can possibly get, as it facilitates... anything but failing. There are plenty of successful - and dare i say 'happy' - people out there with bipolar disorder, because they manage to keep a tab on things and themselves. Life is no piece of cake, but there is very little you can't achieve if you keep yourself well in check, as if you were your bestest of best friends even if, at times, you might not like yourself very much.
It is of prime importance to stick to the medication at all times. Even if you think it's giving you issues, headaches, whatever - do not alter the medication, do not stop taking the meds. Discuss things thoroughly with your healthcare professional. You might also want to keep a diary of sorts to better monitor yourself of changes (good or bad), and you might want to prepare for therapy sessions as if your life depended on them, because, in a sense, it really does.
Mildly related - not sure, but have you seen "Homeland"? Apart from the obvious subject matter, I think you might find it to be... inspiring.
Good luck.
