I read your post and it’s clear to me that you’ve gotten caught in a rather exhausting cycle: you go online seeking a place to talk, but instead encounter negative reactions that only leave you feeling more stressed. This is something many people have experienced; it’s not an uncommon occurrence.
stickman hookThe most important thing is not to let the labels others attach to you—such as "troll," "childish," or "problematic"—redefine your sense of self. On forums or other websites, people sometimes react very quickly and without much sensitivity; their reactions don't necessarily reflect who you truly are as a person.
If these online spaces are making you feel worse, you really should consider cutting back on the time you spend there, or perhaps stepping away for a while. Instead, seek out a few "safer" spaces—or at the very least, places where you feel respected when you speak.
Furthermore, if your feelings of "depression" seem to be worsening over time, talking to a mental health professional would be far more helpful than trying to shoulder the burden all by yourself. It’s not because you are "broken" or "have a problem," but simply because you don't have to carry this entire weight alone.
I hope you find a place where you can speak more freely and comfortably, without feeling constantly judged.
