Can hair grow from damaged follicles after pulling my hair and causing trauma to the hair follicles?

Most likely it’s too late for non surgical options but see your physician to confirm. Surgery is likely the best option for long standing inactive trichotillomania. If it has been many many years that hair has been missing I advise my own patients not to waste time or money on medical lotions, creams, lasers and other treatments with little promise of benefit. But speak to your physician. If any doubt exists, a biopsy can be done to see if follicles are present. 

It soulds like you developed traction alopecia as a child. This is often a permanent problem and is best treated with hair transplants

You just might have caused permanent damage to your hair follicles. You could consider visiting a hair transplant surgeon who could help you transplant some grafts over your bald spot.
