What can be done to be less fearful of the dentist? He was rough on me last year and I haven't gone back.

Go back. I am not sure what you mean by "he was rough on me" but i assume you mean he was not gentle during the procedure. Some procedures in dentistry are not gentle. Extractions come to mind. Give your dentist another chance. If you still feel he is too rough, find another dentist. Call your local dental society for a referral. The worst thing you can do is to avoid treatment out of fear.
FIND ANOTHER ONE THA. T's more gentle. Meet with him/her before having anything done by requiring a consultation visit.
