Is it just the teenage hormones??!!

I'm 13 and I have severe anxiety. I was never actually diagnosed but I know I have it. I just need someone to tell me..my mom says that it's just hormones but I just don't know. Let me explain the anxiety I get: fear that someone doesn't like me (like if I had an awkward conversation and I didn't smile when I said goodbye I will replay it over and over in my mind and worry if the person thought that I was mad at them or if I was being bitchy), fear of being alone (like when I shop I usually avoid paying for something without having a friend with me or going to party's without knowing anyone), and panic attacks( I don't know I this counts but I have had two before)

So can someone please let me know in your opinion I it's just teenage hormones or actual anxiety.
