Most of my life I have had a nervous habit of playing with my hair, picking at it, twirling it, smoothing it down, etc.I really need to stop. Like i can see in ppls faces when Im having a conversation that its distracting. A teacher even made a snide comment about my habit in front of the class. It was kind of humiliating for me. I develop this habit again every couple years even if it goes away for awhile. Its like when people chew their nails but for me I am messing with my hair all the time. Is there a good way to stop?? I am pretty sure it doesnt make me look very confident either...
