Please help me :(((

Hi everyone !! . I wanted to talk to everyone today about something I recently went through because it’s really been bothering me and I don’t really know how to handle it. A few days back I was on my period But coming to near the end of it. I was hanging out with one of my guy friends when he suddenly sexually assaulted me. He tried to stick his penis inside of me and he was successful at it since I wasn’t able to get myself out of the situation because he was too strong( he has it inside me for maybe 1 minuet and 30 seconds) . He didn’t ejaculate inside me or anything but I was concerned because I didn’t know if he pre cummed or not. the next day in the afternoon i took a Take action pill from walmart since I was really freaked out and stressed because of everything i was reading online. I talked to some of my close friends about it and they were extremely supportive and caring. But whenever i finally built up the courage to talk to my mom she was extremely mad at me. I guess i can see why she would be mad but it was like she was blaming me for everything which didn’t help my already ongoing depression/ anxiety in this situation at all. i’m totally stressed and just need to hear some advice from someone i just need help.. Thank you!! ( ps: i posted the picture of my cycle calendar this happened on July 2nd)
