I got threatend by an 23 year old woman on the bus

I tried to explain I have autism and tics but she went really mad and carried on threatening me. And then threatened to beat me up yet she had an toddler with her. And she made fun of my apparence saying I looked albino and she lives near me because she got off at the same stop as me. I wasnt even laughing at her , Her toddler was acting up really badly and making weird noises so I smiled to my dad and my dad tried to explain but she told him not to start when he was only trying to explain.
