How do i tell my parents and 프렌즈 that I want to be an actress?

Just casually slip it out in the middle of a conversation. Sort of like: "Y'know, I'd 사랑 to be an actress".
Trust me, just say it, then it's over and done with. Better than hiding your dreams from the people who care about 당신 most.

I'm sure it will be fine! Everyone I know knows that I've wanted to be an actress all my life, and I know that some of them probably don't think I can make it. But they've never seen me act, and I'm determined that I'm not going to let someone else's opinion getting in the way of my dream.

I know it's harder to say than people make out it is, but honestly, blurt it out as soon as possible, otherwise the 더 많이 you'll worry, then the harder it will be to say.

당신 say...
"Friends and family, I want to become an actress."

Who knows, maybe they won't care.
또는 they might say something like what a parent, such as "whatever makes 당신 happy"

Just tell them!
Being an actress isn't silly. Look at all the great 영화 we have because of actors. Your 프렌즈 and family should accept 당신 no matter what 당신 do. So don't worry, they won't laugh.

I wanna be an actress too :D My family did laugh at me, 더 많이 concerned though. They think I'll eventually get into drugs and stuff but hey, believe in yourself, yeah? :D When you're about to give up, remember why 당신 started. (:
