I've had two false allegations during my lifetime.

Once for child molestation,  once for rape.  Both happened when I was a teenager, and both were proven to be unfounded.  For the first. he only mistake I made was pissing off the wrong girl.  The second,  I was a scapegoat for a girls promiscuity,  and an easy target.

They ruined my life at the time.  Nobody verified or gave me the benefit of the doubt.  Instead a got a lynch mob,  and cold silence after--  Nobody at my school talked to me for months.   It cut me so deeply that I was irreparably damaged,  and since then I find it impossible to emotionally invest in people.  I'll never recover from the way people treated me during that time.  Even after it was all proven to be false I was treated differently.  It taught me hate and contempt, and just like that--  It changed me forever.
