My depression and intrusive thoughts actually got worse during the redditpocalypse. But that was, at least in part, coincidental. A lot of life stress stuff started happening at the same time, and my usual coping mechanism for when things would become too much (scrolling through reddit) was seeing a rapid drop in quality. After approaching a new low, the stressful stuff started subsiding, and things are mostly better now. There are some aspects about yourself that you can't change, but you do ultimately choose how you react to, cope with, and manage these issues. I will have depression and ADHD for the rest of my life, I but I can choose to manage things in such a way (taking more time for myself, having a better diet, being more active, etc.) that these "attacks" are less frequent.
Keep it up, buddy. I am currently being assessed for whatever I may have (ASD or ADHD are the top contenders...) so I kinda feel you on that. The same thing happened to me. Reddit was my favorite social media site besides YouTube and Telegram if those count at all, but once Reddit'd blackout started, my mental breakdown started because I got into a heated argument with a few moderators. I made fake profiles, harrassed them to make them listen to me, and sent disturbing messages to them. I am much better now... lol
