Is it normal that i push/poke the ends of my hair between my fingertips all day

I sucked my thumb until I was 11 and did this hair playing thing with it. here's the hair playing part still going on and I'm 21 -----> I take about and inch thick of hair and press it between my fingers so it's pokes. Almost as if I had an ich. I make like a pointing motion with my index finger (or whichever finger) and press the very end of my hair against the very bottom of my finger( between both fingers) I also press the ends of my hair against the sides of my mouth and sometimes my cuticles. Wherever i do it, my skin must be taut. So i move my mouth to the side or pull fingers away from each other. I do it all the time, literally. Like at least every 5 minutes. It seems to calm me down.......I feel like I look like such a weirdo tho and ppl think im eating my hair
