PLEASE HELP! -- reputation?

I went through some traumatic things and it really effected my mental health. I had no self respect, or self control. I did some stupid things in my past and those choices made rumors about me very easy to believe. I recently started taking antidepressants and they have started to work. For the first time I'm seeing my life in a whole new way! I've changed but my high school past (and rumors...old and new) still come back to haunt me. I deleted 1,100 people from my FB friends and deleted any pictures that were suggestive. But I'd really like to know what else it is I need to do to get a good image back! I'm not the same girl that I was, but people still see me that way..especially one's who don't know me personally. The guy I like has recently become wary of what kind of girl I am because of things people have told him, mostly untrue. He's a good quality guy, the kind that wants a good quality girl..who I am, but haven't been in the past. I'm so tired of my mistakes ruining my reputation and want the world to see who I AM and who I could be, not just who I've been. I've decided to give myself a 2 drink limit when I go out, as to not fall back into any roles I used to fill (ie wild child saying provocative things). What else do I need to do? PLEASE help.
