No, you don't sound like you have bipolar disorder. It sounds like you're just moody, and that's absolutely normal, especially if you are a teenager. Take it from someone who does have bipolar disorder and has been officially diagnosed as having such... Bipolar is not just being "happy" and "sad". Depression for bipolar people is MAJOR depression. Feelings of worthlessness, helplessness, guilt..usually lasting at least 2 weeks. During my depressed phases, I will lay in bed for days without leaving my apartment. I will isolate from people and tend to self-injure to deal with the feelings of guilt and worthlessness. And mania is more than just feeling happy. When I am manic, I feel absolutely invincible, like I can rule the world. I spend money to the point where I find myself in serious debt. I partake in risky behaviours like pissing off the wrong people, driving 30 miles over the speed limit, basically doing risky behaviours because I have such invincibility in my mind. Plus, I troll like a mofo when I'm manic. So, to make a long story short, I doubt you have bipolar disorder. I think you just have normal hormones.
