That totally sums up my middle school years. It wasn't until a week ago, literally, that I finally found self-acceptance. And I'm currently a 17-year-old Junior in high school.
To give you the honest truth (from my own point of view), it is going to take awhile to find the place at which you take yourself as you are. I thought I'd achieved it last August, only to have doubt, anger, and raging self-hate come back to kick me back into submission. It's a long, painful, and repetitive process that requires a LOT of work on your part. The thing is though, you don't have to suffer it alone. Maybe if I'd realized that I'd have healed a great deal quicker from my own experiences.
The way I see it is as follows: No one label will ever apply fully as they are all rather arbitrary names our convoluted society dishes out to people who exhibit certain traits; doing away with those is a healthy choice. If, however, you want to be seen from a certain standpoint, put yourself in the category of Yourself. Be who you are, cause no one else is going to be you. Let compliments feed your self-esteem, and don't be afraid to cry or ask someone to help you out.
Also, I've found that journaling helps a great deal with any negative emotions - and it also provides the opportunity to look back on your happy moments too. I've been journaling, every single day, since 30 June of last year, and it has helped me enormously with my many little self-created problems.
Anyways, good luck and all power to ya!
