What age did you realize that not everyone will be happy for you when you succeed?

I was doing an internship one summer (not paid) and one of my girl pals (let’s call her Britt) wasn’t very impressed. I volunteered at a preschool for work experience and I asked her, “Isn’t that great?” Britt just shrugged and said, “Meh. It would have been better if you got paid though.” I mean yeah but still she could have said, “I’m so happy for you.”
My two best friends were happy for me but they said she had a point.
One time I was doing a play but my dad wasn’t really impressed. I excited told him but he was like, “Hmm. You made the play huh? Okay.” And walked off. I was like, “Aren’t you happy for me?” And he bluntly said, “No because them I’m going to have to come pick you up everyday. That’s just great! Plus plays aren’t my thing. Don’t even think about wanting to become an actress because being one is rare.”
Wow…..
Then some of my cousins wasn’t impressed about my painting and said they’ve seen better. They don’t support me being in college and think I’m going to fail. When I passed my first two classes, they thought I cheated because they think autistic people can’t go to college.
I think at 16 or 17 that’s when I realized not everyone will be happy with everything I do or support me.
I cried to my sister and she said, “Well there you go. You just learned a life lesson. Not everyone is going to be happy for you with everything you do. Dad isn’t really into plays so don’t give him a hard time, although she should have shown more support. Just because we’re family doesn’t mean we’re going to agree with everything you do but your happiness is more important and don’t let anyone spoil that for you. That’s life. Welcome to reality and stop living in a fantasy. Buck up sweetheart. You gotta toughen up.”
