For the past 2 months I've got into the habit of closed mouth coughing all the time. Its pretty satisfying doing it but its getting outta hand when I start doing it I can't stop unless I consciously force myself not to do it. I probably look like I have emphysema or some other lung disease. Is this what stimming is or have I got OCD? This isn't the only compulsion I have, I also regularly grind my fist into my palm and rub my forehead with my hand rotated so that the fingers are vertical. Do these things sound like stimming or are they something else?
It could be stimming, could be a tic. Tics are only mildly voluntary. My experience of them is that they just kind of "happen"--I do them before I have a chance to think about them. For me they involve jerking my head in a sort of odd way, or occasionally a whole-body spasm, very brief. If you have a whole lot of tics and they're really constant and long-term, a doctor will diagnose Tourette's, but tics are so common in general that there's no reason to worry about them if you only have one or two and they don't interfere.
Stimming is usually voluntary or semi-voluntary. I say "semi-voluntary" because it's quite common to do it without thinking about it, as a sort of default movement, just like you might sit without thinking about it or walk without thinking about it. It's also common to need stimming to get into emotional or cognitive or sensory equilibrium, so it's voluntary, but necessary, like eating or drinking.
Bottom line, if it's a stim, it's harmless; if it's a tic, it's harmless. So I wouldn't worry unless you are doing this often enough and in situations where it distracts others. In that case you might ask a doctor for advice; they do have meds for tics, but they're generally a trade-off because the side effects might not make them quite worth it. Sometimes it's just better to deal with the tic as it is. And anyway, people get used to it; the guy who sits next to me in one of my classes has a vocal tic like clearing his throat every few minutes, and we all pretty much just got to the point where it was normal and we ignored it by about the second lecture.
