I realized that self-diagnosis is bad and it make it dangerous for mental state.Last week I've been struggling about my unknown mental disorder but then my elementary classmate finally told me that it is bad to self-diagnose.She's having a terrible day and can't do the worksheets from school the same as me.She told me that I should do coping mechanisms and if after I do that,maybe I should tell her that I finally cope and it makes her feel better instead of worsening her mood too.
