Symmetry-ish Compulsion. OCD?

Hello,

I think I have an issue, but I couldn't match it with any description of mental issues I saw online. Would anyone here help me identifying it? The closer I got is OCD, but I am not sure.

Whenever I am sitting or laying down, I can't stop moving. But I tend to move in some patterns, usually anti-symmetryc, e.g. if my foot is going up and down (in this order), I will move another part of my body (usually the hand/fingers) in the opposite direction, down and up. Sometimes I will move three parts of my body, like foot, leg and hand. When it happens, the middle one (physically; in this case, the leg) usually moves in the different direction.

I am also almost always gritting my teeth, but maybe this is because of the braces and the new, ever-changing shape of my teeth.

Another thing is the floor. I tend to step the same amount of times on each color of floor with each foot, e.g. if I step 2 times with the left foot on a certain floor, I "need" to step the exact same amount of times with the right foot. I have this for like 10 years (I am 22 now), but maybe 2 or 3 years ago I (unwillingly) added shading into the process, so if I step in a floor with low light, I need to step with the other foot in the same floor, with the same light. Something that eases this for me is that I rationalize and get to the conclusion that every floor that I step has the same amount of light, which is none, because my own foot makes a shade on them. But I am pretty sure that rationalizing is not good, it is just a way I explain myself that I don't need to go back to a place just to step on a certain floor.

The thing about the light is especially bad because when I am driving, I tend to drive the same way, like if the left wheels were my left foot, and the right wheels my right foot. Something that also gets me uncomfortable when I am driving is when the lane is wet, because only one side of the car drives over the darker, wet part of the lane, while the other keeps on the dry part. It happens because of the system of drainage.

I also find it very hard to make new friends and making small talks; on the other side, having real conversations is something I can do very easily, but it only happens with people that I am intimate with. But I think it may be something else than the questions about symmetry. Right?
