Do I have bipolar disorder?

Hi,

What's wrong with me?
When I was in elementary school, I was bullied a lot. I never got beat up or anything, seeing as I'm a girl, but other girls would write mean things on the bathroom walls about me, and call me names, because I was a few grades ahead in many subjects.
I had very few friends. I was quiet, and read books instead of watching TV like every one else. I lived a sheltered life in the country, and knew nothing about anything. People scared me. I was extremely self-conscious. I had nightmares, and I cut myself in 4th and 5th grade. I wasn't emo or anything, I just liked to watch the blade cut my skin.
Then my parents transferred me to a community school for 6th grade through 8th grade. I got better there. I stopped cutting, and people were nice to me. I became very outgoing, almost silly. I learned more about normal stuff, like cell phones and makeup and television and the internet. I made friends.
Then everything started to get a little weird.
I was happier, except for my moods would change constantly. Some days I would be extremely depressed, and some days I would be extremely hyperactive. I have troubles getting up in the morning, I get distracted easily, I'm impulsive and restless, sometimes I can be aggressive or lethargic or depressed, one right after the other. I'm constantly changing my energy levels and emotions subconsciously; sometimes every hour I'm a different mood. I cry extremely easily, and I'm super-sensitive. I'm also a little OCD, I daydream a lot, I have really bad short-term memory, I'm unorganized, I can be manipulative and bossy, I'm a compulsive liar, and I have even thought of suicide.
The aspects I listed are all symptoms of Bipolar Disorder. BD tends to occur more often when a family member has a disorder of some sort, like my sister and aunt. My family also has a history of mental issues, such as autism.
The listed symptoms, despite their number, had never dramatically affected my life in the past.
But now I'm in high school, and people are starting to notice. Some of my friends flinch away when I come near, or avoid me. My parents ask why I'm depressed all the time. My usually perfect grades are falling. I'm not sad, I'm just... numb. I'm considering cutting myself again.
I'm deteriorating.

Any help will be apprecited.

I didn't find the right solution from the Internet.
