Thanks for the replies, guys. When I meant tics, I was thinking of facial twitches, uncontrollable blinks and the like. I don't experience those myself but I get worried that I might get them someday.
One thing that's probably considered a tic that I did was that, whenever my neck ached or made a poping/cracking noise, I had to throw my neck back and stick my chin forward.
I think I started doing it because I didn't want my neck to ache or make a noise, but since it wasn't something I was in control of, like I couldn't prevent it or anything... I did that "tic" as a reactionary act.
I became aware that it's something I'm doing often when one day, this horrible fat bitch was making fun of me in front of this popular guy in a sports car. Fatty probably thought she was cool. She was imitating the movement I was doing, like sticking her chin out like I did and told him to look at me. And he looked but when he realized I was aware of what was going on, he pretended he was looking at something else. She, however, was looking straight at me. And they were laughing.
I was really hurt by it at the time. She works at Walgreens and that's where it happened, outside of it. Later on, I thought I should have turned around and yelled at her, like calling her a fat bitch and saying "yea go ahead make fun of me, but no matter how hard you try by making fun of me, he's not going to fuck you because your big pus*y is too fat and loose" ...lol.
And when I wasn't angry anymore, I thought about going back to that walgreens the next day and looking at her in the eyes and telling her that I knew she was making fun of me and that it hurt. And then just walk away.
In the end, I didn't end up doing anything to her.
I tried to stop my tic after that day. It didn't happen right away but after a couple weeks, I did stop doing it all together. It never came back.
I'm sure that that bitch at walgreens is still fat and still acting the same way. Oh well, some things you just can't change. lol........
