self diagnosing?

Why do people act like self-diagnosing is so harmful? like it's understandable if someone was going around and spreading misinfo about an illness and romanticizing it, but most people who self diagnose aren't doing it for attention and aren't making tiktok accounts dedicated to their illness, it's just that the ones who are doing it for attention GET THE MOST ATTENTION, I self-diagnosed with depression, and guess what? I just got officially diagnosed with severe depression, it's not that hard to do as long as you use trustable sources(hospital sites, gov sites, DSM, etc.) but even if you self-diagnose, try your hardest to get an official diagnosis

PS, most people who self-diagnose don't have easy access to health care (including me)
