    From this list, it is apparent that you know absolutely nothing at all concerning mental illness. You seriously think OCD is worse than schizophrenia? Have you ever taken neuroleptics? Or how about treatment-resistant psychotic depression? Ever experienced that?
    You are an ignorant maggot.

    Dyslexia is not a mental illness you fud. I am yet to meet someone suffering with dyslexia who mixes up sounds…. also I am dyslexic and you have mentioned nothing that relates to me. Stupid people and dyslexic people are not the same. To put dyslexia on a list for mental illness is in itself idiotic 🙂

    So Dyslexia is apparently worse than Schizophrenia, Depression, and Anorexia? What a joke lol, Autism Isnt that bad either, they pose no risk to themselves, the only problem with autism is the ignorance of those that dont have it

    well i think dyslexia is not worse than schizophrenia as it can be cured by proper guidance and teaching but schizophrenia is very worse as it leaves the person with no desire to move forward in life

    hi my name is “stephen” (an alias, I don’t want anyone to see this) and i was diagnosed with paranoid schizophrenia last year, and suffered from severe OCD for years before the onset of my schizophrenia but it was treated with Prozac and the symptoms all but subsided.

    I can tell you, from experience of both afflictions, that schizophrenia is absolutely, unbelievably, unquestionably worse in every possible way.

    let me explain.

    OCD afflicts your day to day routine with rituals and obsessions that bother you in your daily life at school or work or whatever. it’s a big hindrance on your life, no doubt.

    schizophrenia plagues your mind with a neverending uncertainty of what is real or not real. the amount of obsession you spent on your obsessions is negligible compared to the amount of obsession you have trying to validate your delusions and living in fear. in addition to this, your life simply falls apart. I was kicked out of my high school (I’m young), lost pretty much every personal relationship I had except for the ones that had to support me like my parents and even that was irreversibly damaged by mistrust and genuine hatred for months.

    this doesn’t even begin to describe the effects of the anti-psychotics i was given. they completely drain you of your very essence, what makes you you. sure they can rid you of hallucinations and delusions for a short while but they never worked long-term for me and when they did I was merely a shell of a person.

    I can tell you that schizophrenia is not only hands-down the worst mental illness, but one of the worst illnesses of all. Living in uncontrollable fear, doubting everything, hating everything, in addition to the anxiety in daily life is unbelievable. I wouldn’t wish it on the absolute worst, stupid, ignorant, arrogant, malevolent cesspool of a human being in the world. It’s worse than any perceivable hell.

    Luckily I finally found a helpful neuroleptic after months of switching and such called thiothixene which helps enough for me to distinguish between reality and the unreal. Things are getting better.

    Good luck with your OCD, friend! Life can get better no matter the circumstances 🙂

    so dyslexia and ocd are worse than mpd and schizophrenia? lol no. i’ve been living with mpd since my early teens, it is hands down the worst mental illness you can have. schizophrenia comes at a close second, my brother had it.
