Could I have Bipolar Disorder…?

I've been battling with acne all my life and I've been made fun of over my skin, nose etc. so it's gotten really personal. It's affected me a lot because I hate myself and have no confidence which is why I can't participate in class discussions or interact with people very well. Everyone looks at me as secretive, distant and dull.

For as long as I remember, I've been judged and made fun of based on what I look like and I'm pretty much always in the dark; I feel like no one cares about my existence. In the last year or so, there have been times where my sex drive went through the roof..I did all sorts of things on webcam for strangers and I felt like I was making foolish decisions. For a while I was normal till winter when I got depressed for a month.

Right now, my mood is so unstable it scares me. It rapidly cycles; one minute I'm talking a lot faster than usual and I look like I don't have a care in the world (Extremely irritable at the same time as well) and literally, in 2 minutes, I just go quiet and stare into space like someone whose dreams just got shattered. I've also heard things that weren't there 4 times till now..possibly more.

It hasn't really affected my academic performance in school..I'm doing quite good. But my relationships with everyone are so severed and I feel so helpless and lonely. My mum agreed to let me change my school, do everything it takes to fix my skin and fix my nose and I was so happy for a while. But the mood swings haven't gone away. At first I thought maybe it was because of low self esteem and my school and I was just really stressed..

..But turns out, it hasn't gone away. What's wrong with me?! D:
