then a month long break god bless u college

I'm staying in texas another semester, then I'm going out of state and it honestly scares me so bad.
im scared of leaving my own room much left my own state.
I'm likely going to Savannah College of Art and Design, since thats been the goal since i was in middle school.
I don't know if I can make it though.
Concept art has been my dream since I can remember but the more I see what a faced paced industry it is, i just don't think I can do it. And I want it more than anything. I want to see my designs used in movies and t.v. shows.
I want to be recognized for my creations.
Im scared that i just flat out can't do it. My fallback is being an art teacher which is fine I guess.
Scared of not making it
