Anxiety of pretty much everything?

[Oceanrer]

Ever since the summer started, I've been acting different. It all started with the fear that I would sleep walk and hurt my family, then it went to my sexuality, and now its everything. I'm afraid of becoming depressed, hurting myself, that my friends don't like me anymore, that I will become emo or goth, that I'm the weird one in my cast right now (I'm participating in a musical right now) and so on. I know deep down that these are fears but they seem so real.
One of my biggest fears is getting help. Lets just say when I was younger, I was an awful child. I hurt people and yelled at people and made people afraid of me. To this day I regret everything I did and wished it would go away. Thankfully I got over it and now I can't stop caring about what people think of me. I always try to dress normally, act normally, and just be normal. I hate being the spotlight and everyone notices me. During the school year it got better and I eventually came out of my shell. During the end of 7th grade (I'm going into 8th), I was very happy and never got anxious.
Time-skip to now I'm having a day where I'm freaking out about everything, and I hate it. It could just be the hormones flowing around in my body from puberty or the time of the month, but I want help. I wanna stop feeling like I'm the only one and that even my family thinks I'm mad.
