I feel lost on what to do now?

Well during my childhood, i was abused by my parents. I grew up in the bad side of jersey. I just recently got a job as a custodian at a elementary school. Its a simple job but i feel as though im smarter than the people who go there ( like if i see an unsolved equation on the board ill finish it). So as im cleaning out the rooms one night, i see one of the teachers is still there. I turn to leave her alone but she stopped me. We got to talking and her boyfriend just left her. I tried to comfort her and we ended up making love on the desk. So after that we talked some more then i told her one of my darkest secrets. It was that i do coke from time to time. Instead of comforting me she just cried and said i was just like her ex and left. Now i see a therapist and im lost on what to do now.
