I have much the same issue as many here with pulling my hair.
It started about a year ago and started slowly pulling this one spot behind my ear and in about 6 months i had a clearly noticable bald spot on the back of my head behind my ear. It was really embarasing and I did feel ashamed of myself because i have such nice hair. I was really worried it wouldn't grow back. Fast forward to 6 months from now, it's starting to grow back a little but not as much as it should and stupid me, I've still been pulling although not nearly as much.
So tonight I bought an electric shaver and shaved my head military style. I needed to stop the pulling and see if my hair would grow back. I can feel little stubs on the back and and I can see the folicles where it hasn't grow back, ti's not shiney and bald yet except for one very small spot.
When I shaving my head, I saw my own hair in my hand and how shiney and soft it was, and the color, I've never seen it look that nice and I felt so bad that I was ruining my hair. I don't mean make anyone feel bad, but I think I hope if we can learn to love our hair we will be more motivated to break these habits and protect it. I did what I had to do to protect it and I hope you will too.
I'll post an update in a month or so when it grows back to see if my bald spot is still there as it was before.
Good luck to everyone, I hope the best for you all. We can beat this.
