Idk if have tourettes

Ever since 7th grade I think it might've started, I started snapping alot until I got blisters and I stopped. But a after 8th grade I started this thing where I made weird noises and stuff and idk why, I was able to stop it for some good time but now it's back and way stronger. Yeah I have no idea if this is real. Even people have called me some things. Is there a way to test if u have it because I cannot believe I have this and just wanna make sure.
