Going back to my hometown after a long time

I'm going to the town in England where all my friends live and where I grew up (I moved to Florida, USA, two years ago). I haven't been back in almost a year. And I know I'll get to see all my friends and family and have loads of fun. And I should be excited.

But instead I'm really scared and anxious and I don't want to go and everything.

Because my friends might not like me for not writing enough letters. They might have changed. I might not get to see them enough because they'll all still be at school, and all my brother's friends won't, and I should have waited till July for me to go, but I didn't want to fly on my own. And it'll all be awkrard. And they'll have made closer friends then me.

And I'm also really focused on school finishing and exams and whats going on here still. And school breaks up on thursday. and then I think about the summer. And how I leave on Saturday but haven't thought about it at all. And I get scared and I don't want to go.

Help me please.
