Got told I'll never be loved because I'm autistic and to kill myself

21F. I got this message on reddit. I didn't save it I deleted it straight away because I was so upset, I just want to exist :/ they said no one wants an autistic woman because they're all ugly and emotionless and to accept no one will love me and to kill myself.

It's been bothering me all day and I had a internal meltdown over it, I don't understand why we can't just exist without people wanting us gone.
