Do I have Aspergers?

So I'm 17, and since November last year I've been thinking I have Aspergers. I notice symptoms like i don't make friends, I am very poor at my social skills, I never talk in school unless I'm called on or doing a presentation, stuff like that. I just like they say about people with Aspergers too, I have an obsession, gymnastics and celebrities, yea what teenagers don't like celebrities but still I'm just super obsessed, I love all of them, except Miley Cyrus because she's a disgrace. I'm also sensitive to noise and I find a lot of things too loud or annoying. I get mad and freak out over the smallest things, and when I get really mad, I will just sit down and stare… Like pouting. I talk ALOT. Only around people I know. I also go by sustain routines like waking up in the morning, going to bed. I even have a special routine for brushing my teeth. I have not told anybody I think I have it, but my mom did say a year ago that I had like a mild adhd when I was younger, could that be mistaken for Aspergers? I did think I was dyslexic when I was like, just 13, but I know I'm not now because I'm really good with vocabulary, gra,, at reading and that kind of stuff. I also took an online test and it said I have it, but i don't know if it will be accurate…
Added (1). Sorry about the typos from my stupid iPad, sustain is supposed to be certain, and gra,, at (I don't know why it did that) should say grammar
