Issues on domestic violence ault, if the person wants to drop charges, how does that affect the offender?

I am a female, a wife and a mother, who got drunk one night, suspected being drugged in a bar, got violent and scratched my husband's face with no recollection whatsoever. He called the cop that night, they came and arrested me. Later on, he wanted to drop charges, asked the victim advocate to do so but they said to tell me, just go to my court date and they will probably cut me a deal. I need to know since I am waiting to finish my M.A in health science how much this will impact me in life. I've never been violent before, never hurt a single soul other than that fateful night, will I still be able to pick up with my life?
