Hi. So I decided to go to an all girl high school desperately wanting to stop being scared around girls and gossips.
At this moment things started to change and everything seems better. EXCEPT when i'm around this one group. Those popular loud girls makes me feel uncomfortable being myself. They're actually nice people and they talk and care about me a lot, but i'm the one who is like putting an invisible barrier between us.
Whenever they talk to me I can't be myself, i respond weirdly or i just say confusing stuff and it makes me look weird even though i'm not. At one point when they were being silly and they asked me to join them i was so scared i wanted to run away. But i knew there will never be a solution that way so i approached them anyway. So i felt really awkward and i actually froze, i couldn't even do nor say anything right and i felt like wanting to disappear.
It has been 2 years being around them, i don't want to keep doing this

I don't want them to think i hate them or anything, they're so nice to me and they did anything to get close to me but it's as if i just shut them down and gave them negative vibe. I don't want this, i just want to be friends with them normally and talk to them like i talk to everybody else. (I'm actually a really silly and outgoing person too). Please help me deal this damn problem.. Thankyou for reading btw!
