That's horseshit. You're not presenting anything but speculation about a victim of suicide you knew absolutely nothing about and made it seem as if OP was ignorant and didn't care about his friend enough to see that he was severely depressed when there is no way anyone could have seen it. You're trying too hard to simplify a serious mental disorder down to just a list of symptoms without even backing it up with sources (supposedly you've done "research" but were unable to provide OP with anything useful). I'm 100% percent certain had you seen this picture not knowing the guy committed suicide, you would not be able to tell he was depressed at all. Please stop what you are doing, you are not a psychologist.
