Do i have OCD

Ever since I was really little I'd have to touch things with both hands or else I'd feel extremely uncomfortable and tingly. For example if I held my pencil and was writing I'd have to frequently switch hands just to feel the pencil in the other hand. I wouldn't write with my other hand. I just needed to feel it. When ever I touch one side of my body I must touch it the same way on the other side. Whenever I look at a clock (literally every single time) I try to find a way the numbers correlate. For example right now it's 4:37 so 4+3=7, 7-4=3 and so on. Whenever I'm watching a video online I always look at the time and keep watching the the minutes go up until they completely match up (if the video is 6 minutes long I must look at the video when it says I'm 3 minutes in and 3 minutes remaining) if the video is an odd number like 6:01 I do the same thing but say 3:005 in my head. It makes me feel satisfied. What's wrong with me? Also I have severe social anxiety (I've been diagnosed)
