Am I crazy? Or just bipolar?

What is Bipolar? I may have this condition. For quite some time, I noticed that there have something was wrong with me. Sometimes I am very active, even aggressively active. But then, in a few days, I get so depressed that I can't get out of bed. Or is it some sort of personality disorder that I have?

I am sure nobody here has the right to judge this or suggest any medical diagnosis for you. This is the sole responsibility of a qualified psychiatrist. So your first step is to get to the specialist if you suspect that there's something that's been wrong with you for a while. Although you can start by reading about the difference between BPD vs. Bipolar since that was one of the questions that you asked.
