Sexual assault

I was drunk once and in our town was a festival so there were a lot of people and it was midnight so I called a “friend” of mine to drive me home. We walked a bit so that I could sober up and got to a park nearby, then without saying anything he touched me from behind. I was wearing a skirt but still…then a few minutes later he did it again. I’m on vacation now and my uncle slapped me as a joke on the same spot where I’ve been touched. I’ve talked to a therapist but I still get very uncomfortable around men.
Any tips?
