Going into Junior High? totlay scared and nervous!?

we had an orientation yesterday and the school was so big! it was just so... confusing. i kept getting lost EVEN WITH THE MAP! and gym scares me, the whole dressing down thing. and showering. my mom, when she was in junior high, they made them shower. she just wrapped up in the towel and splashed herself (like all the other girls) cuz they checked her. i am SO nervous! i hate changing in front of my MOM! let alone some 30 girls i don't know! and showering! EWE! and i don't have a ton of friends... namely 2. so i have 2 friends. i know a lot of other girls in the other schools but non of them will remember me. i have changed so much i barely recognize some my self! and the likeliness of us getting the same cles at the same time are slim to NONE! and on of my friends isn't even gonna be going to my same junior high! she is gonna go to a charter school or be home schooled! so ONE friend! i know other ppl and have other friends i guess. but she is my best friend! i just don't have a TON of confidence. i mean i used to but i am called so many names and put down by so many ppl. i know, i know just cuz they say it doesn't make it true. but it still hurts. kids r jerks
