numb from abuse

I fell asleep at a friends house and their guy friend came over and touched me inappropriately. I feel numb. Nothing seems to really interest me anymore, I don't want to get out of bed. I feel kind of pathetic. Only my boyfriend and sister know. I asked them not to do anything about it because this boy who touched me struggles with suicide and his parents are getting a divorce. I know that's no excuse.. I don't really feel comfortable with men anymore, I sometimes struggle being with my boyfriend and before this I was prone to anxiety attacks and they feel like they are reemerging. I feel lost and advice would be greatly appreciated.
