Hi dihahey!

I behave pretty much the same as you and had a few different diagnosis as well. Now I am in diagnostic process once more and probably bipolar II as well.

I know exactly what you mean by saying that you "screw up" and then plan to do everything 100 % right. I periodically quit partying completely, start to do sports every day, go on a diet, start studying like crazy and then I screw up one day and everything goes down the drain. I also experience states of very low and very high energy, love to clean when energetic, went through eating disorder and drugs experiences.

Probably the others are really right when they say that diagnosis is not the most important thing, but it can help to treat you with more success.
