New here! Wondering if this is OCD

First, hello! I’m dahlia, dah for short!! (◕ᴗ◕✿)

I’ve heard from some of my friend with ocd that this might be it, so im going to list my habits!

1: I really like the number 3, I normally do things in 3s and hate when things aren’t in 3s. To the point where I physically don’t grab something if its labeled in a number that isn’t 3 (if that makes sense)

2: I do this thing where I jerk backwards when touching something? It’s almost like im hesitating whether to grab it or not but it’s not something I can control. Like I’ll jerk my hand back like 5 times before grabbing something. 

3: I also get annoyed with the average stuff, like if something is printed the tiniest bit off, it irritates me like ALOT. I physically can’t focus on anything else but whatever is “messed up”, and I’ll constantly keep looking at it which makes it worse because looking at it makes me… even more upset

these are the main three I can thing of at the moment (hehe, three :3) but I’ll get back if I think of more! ⊂((・▽・))⊃
