Please help my life..

I'm 20, and this half year I just rent an apartment so I can go to my office easily. This is my first time living alone. Tbh, I work in a office where I'm the only girl, I have no female friends there. So in the past 5 months, I was so lonely I don't have any friends so I decided to try a dating app. The total guys that I met is 5 guys, and I hook up with them, I didn't ask for a hook up, it was just happened (we always use protection), But now I think I've slept with too much guys so I delete the dating app. After I delete it, I feel kinda empty, I don't know what to do, and most of the time I just feel like something is wrong..

These days I can't get enough sleep and I always woke up at 1 am, thinking am I addicted to that dating app? I don't know.

I had so much things going on for that past 5 months, I went through sexual harrashment in my office (verbal), and it stressing me out (I did cry once bcs of it), I hook up with 5 guys but always use protection, it supposed to be just-a-date, but then end up on the bed even when I said I don't want to do it.

Ever since I live alone, I start my drinking habit and in the end I always regret it. Its hard for me to take control of my life again, I feel like nothing seems interesting and I'm starting to feel nothing.

My questions are, is it bad to hook up with 5 guys? Do you girls think that this dating app is a negative thing FOR me? How do I handle my anxiety attack that always wake me up at 1am? How do I keep my life together? ;-;

Please.. any answer would be nice..
