 A few months back, I followed this guy on social media. He was a  teenager like me, he was part of the trans community like me, and I  thought he looked really cool. One day, I decided to DM him because,  like I said, I thought he was cool. I'm technically a pretty friendly  person, so I really didn't hesitate. I was very cautious not to give  away any personal information, like I would with anyone. But it wasn't  good from the start. He was very, very upset and depressed. I am  depressed too, but not like this. He droned on and on about his issues  and how he thought he was ugly. I listened and tried to make him feel  better, but he would reject whatever I said. So I shared a few of my  personal experiences, to try to show I also had depression. He told me  to go to hell, that I wasn't depressed, that I didn't know anything  because I was a "kid," and that I didn't know "real pain." Also, in a  short-lived conversation about our sub genres, he called my sub genre  (I'm punk) and my hero "disgusting." He kept saying these things to me  and I just felt awful and manipulated. I tried standing up for myself  numerous times only to be shot back down again. Through it all I tried  to keep my morals and have respect because I know that if I kept my  morals he wouldn't be able to use my behavior against me. After a full  day of arguing, I was so beaten down I relapsed into self harm. I ended  up blocking him. At the time, I thought it was just a single argument  that was good for me and I would forget about it. But now, months later,  I'm full-on traumatized and I avoid showing people my depression or  expressing my sadness because I don't want the same reaction. I get  really triggered by the word "ugly" (just typing it makes me super  upset) and the text-talk type of talking he used while writing with me  (not like "lol" or "gtg," but shortening words like changing "are" to  "r" and "you" to "u") also triggers me horribly. Whenever I think of him  I shove the thought out because I feel like he doesn't deserve my  brain-space, but now it's getting harder to do that and I'm even having  nightmares about it. I think it's stupid cause I only had one interactions and only knew him for a day. And I'm also really scared about posting this because what if he sees and I have to talk with him again? What should I  do?
