Will it ever come back?

I am a male and whenever I grow out my hair on my head I start to pull. I have been pulling my hair on my head and my hands for 5 years now. I have 3 bald spots out of 5 total. 2 of my bald spots you can hardly notice, but it did grow back a little differently. At least I have almost 80 percent of my hair back in those two spots! But the other 3 are much smaller and newer, they also seem to be taking forever to grow back. Will my bald spots ever grow back to where it is unnoticeable? The last two did very well and they were much bigger than the ones I have now. I would like to have a normal haircut instead of a buzz that I usually give myself. My family has been terrible about it and has done nothing to help me, in fact they brought me down even further. I was wondering if my bald spots will come back to recover at least most of my hair? Do they grow back? Please someone tell me who has experience if they will come back or do I just have false hope? I dont pull on my hair that much anymore, instead I pull the hair on my hands and feet which I dont mind too much. Thanks for any help anyone can give me!
