trigger warning

When i was 16 I went to my friends sleepover we all got super drunk to the point we barely new what we were doing and she tried to make me have sex with one of the other girls. I think she was sober. I didn’t tell anyone because I knew if i did everyone at school would think i was lying. When I was 17 I worked at tropical smoothie and my boss would make sexual comments and sexual advances at me he was 27. When i told my mom she told the police and they couldn’t find him we also had no evidence. He tried to friend me on Facebook a couple years later. When i was 19 My cousin kept making sexual advances toward me. I told my family and they did nothing. Is that sexual assault? And should I seek counseling I’m 21 now.
