Could I have an anxiety disorder? If so what to do?

So I'm 16 year old girl.

Honestly I don't know how to write all I have to say so please just stick with me.

So I'll begin to say that I believe I have social anxiety. I just can't explain what my body does when I even think about being with people. I'm even in therapy for it. I do feel like my social anxiety is getting better. But I feel like I'm developing other types of anxiety.

Ok so since I was little I be been scared of stickers. I have know clue why. I just thought when I grow up that Itll go away. But no, it's gotten worse. Ive even become really germaphobic and OCD.

And I wasn't like this when I was younger.

I've googled a lot for like a year and found out that sometimes people develope anxiety/OCD at an older age like around 14-16. And that's the age I was.

Oh and not to mention my brother,sister, and even mom have anxiety problems. I feel like since I don't show my anxiety like they did that my mom doesn't think I have a problem.

I'm wondering since they all take medicine for anxiety if I ask my mom to see if I need to get on the medicine. Yes I know medicine isn't the answer. But I need help with this.
