What should i do please help?

i know you'll think im crazy but please keep reading. on the weekend i met tom felton at a convention and this morning i realized that is the biggest highlight of my life. and i realized it always will be... until someone else comes and i meet them. and i thought about it and came to the realization that my life will never be like that. i am going to get a terrible job get old and then die and its scaring the f**k out of me. now here's the really stupid part im 13. 13 years old and i've been crying all afternoon because i will never get an awesome job and be rich. im not crazy that just how i work when i was 7 i would stop breathing in the middle of the night because i would know one day i am going to die. now i could get over it but i don't want to i want to get an awesome job and do stuff. when i get older i want to go into design and sewing and what not so that eventually i can do costume design in movies. How can i do this or at least do something like it that will make me happy
