Help

I hadnt had a crazy night out for 6 months. My relationship with alcohol was feeling so strong and I felt happy and good in life. I felt safe. However last Friday I met some friends for drinks, and when they left, I ended up going and ordering myself a drink and standing alone at the bar. Naturally, I then ended up with another group in the pub and having out with them. After that, I dont remember anything. I remember being told by someone that I had been chucked out a pub, but I have no memory of going in or being chucked out. All I do remember, is feeling extremely extremely manic - like I had done ten grams of coke or been injected with red bull! Somehow was telling me its probably time to go home, and I was desperate to get into another pub. I then ended up in a university where I drank with two guys first at the lobby, then back in their flat. At the end of the night, one of them tried to force himself on me. I have a boyfriend who I love, and that moment terrified me and brought me to my senses. I ran away and left. Since then, the guy has started texting me, finding my Snapchat and trying to add me. Worse is, he goes to university by the station I have to go to for work. Ive tried planning an entirely new journey, but I have to go to this station. Im now having panic attacks and too scared to go incase I see him. I cant tell anyone either, as Im so ashamed and confused by how out of control I was. Im also suffering with PTSD, and have nobody to talk to about g
