Back to school/ Am I being weird?

Hey Beasties, this blog today is mainly me venting my inner frustration......
Right now I really don't want to go back to school. This summer holiday I spent quite a lot of time by myself (BY CHOICE!) and I've kinda forgotten how to talk to other human beings. Curse my incredibly socially awkward soul!

Ugh... I used to be so confident... In the past year I've become a lot more quiet, I just don't know. I'm kind of scared to go back because I just don't know what I'll do.....

I like being around people I guess, my group of friends, but not actually being involved in the conversation. Just watching and half listening makes me feel happy, knowing though that if I do say something my friends will listen and include me in the conversation, but choosing to say nothing.
When I do talk, I can talk for AGES, but yea, I guess I just choose not to unless my input is valid, or worth saying.

Am I being weird? Is this abnormal for a 13 year old girl? I'll be in year 9 (8th grade) when I go back.
Thoughts please. <3
