Currently in an anxiety pit

Hello.

Just for context, I’ve been diagnosed with GAD and Melancholia.

I recently moved to London for my masters and I was so excited because I’m going to my dream university.
I was paranoid about the posts I saw about pickpockets and phone stealing so I knew I had to be super vigilant. The second day of my uni, someone pickpocketed me. He removed my wallet from inside my bag, removed my stuff and kept it back. I luckily realised that my wallet was kept oddly and called him out, after which he gave me my stuff back. (I don’t want to repeat this story, it’s pretty complicated so I’m just giving you guys a gist). This all happened to me on campus. Since this day, I am living in a pit of anxiety. I am so scared of everything on the street, of every person that passes by me and of travelling all the way to uni.

I posted this experience on the AskUK sub, to which people said that this sounded like a generated story and that I was karma farming. I had written the post pretty crappily because of how I was feeling and missed out on a bunch of details, which is on me. Some people were nice too, and I am grateful.

Now, I am struggling. My stomach is constantly churning and I am so scared of this city.
This happened when my bag was on my freaking shoulder. Yes, I was confident and bold enough to confront this a-hole, but I am so so afraid now. I attach sentimental value to things, and don’t want to lose anything. I’m trying so hard to move past whatever happened but I just cannot. I feel so overwhelmed and have no idea how to cope.

I was put off escitalopram and bupropion a month before coming here because I was doing so well and now everything feels like before. I know I am stronger to just be able to handle this and go to uni instead of staying in bed, but the feeling while I am doing all this just sucks. I want to breakdown and cry all the time. It doesn’t help that my family is also not in the same country.

I don’t know what to do. I don’t know how to deal with all this, I just want this feeling to go away.

Sorry if this post is confusing, I am not in the best headspace and I tried to cover everything I could.
