Help...Being scared.

Im 14.And about 4 years ago,I was sexually abused,by a 16 year old.So now...i am scared of guys.But seriously,scared.

I only have 6 guys that i can trust.

-my dad

-my grandfather

-my aunt's boyfriend

-my best friend

-my crush

I had told my crush about the abuse,and he makes sure to talk about stuff when not in biology class.But here's the thing.

I trust him but when he jokingly clenched his fist like he is gonna punch me i really got scared.Like seriously i almost fell off my chair.Then he hugged me"I wouldn't punch you"and it was the equivalent of being shot any second.I know it's affection but still...How can i stop being scared of people?
