Someone, please tell me how I can stop doing these things!?

Ok, so for as long as i can remember I have had these weird ticks where i have to move my head a certain way, or make it so that the rims of my glasses overlap an objects, but mainly ones with moving my neck a certain way, but recently they seem to be getting worse, I keep trying to stop doing them but I just can't so can someone please tell me how I can stop doing them? its really annoying and I know that if it continues it might physically injure me :(
