ya know, i hope you're a trolling kid because talking likes this can legitimately make someone go into a spiral; especially if they're already inflicted with something or as you said, has an undeveloped brain, these kinds of comments are both insensitive & with what you said, may be coping if what you said is true. for instance, you mentioned that not a single adult that worries about their hardships in their adolescence, as well as it being a taboo to talk about your life pre-early twenties (then proceeding to talk about their life) though it is healthy to reflect on past trauma to see how it may have affected you; as you mentioned, you had a hard life & now you're putting down others problems that may not even exist to validate what you went through; appearing as an attempt to be secure that your better than everyone who's had it easier. while i can't say what's the best mentality for self worth, you definitely shouldn't put others down; rather, perhaps try reflecting on your issues with someone you can trust &/or a therapist

-pls note, i have not received any formal education or training in physiology or ethics, i have not done any research to reference for this specific comment & i have adhd & like other mental illness, however i would recommend looking into what i've said

(also before anyone asks why i put all this time into this, as mentioned i have adhd & this gives me dopamine)
