Go to the websites of the companies you want to work for and read their "career" pages. Many of the top companies are always looking for new talent, and offer internships to get you in on the ground floor. You can even go with start-ups and learn the programs/processes before heading to the big time. And many of those smaller companies aren't in LA where a glut of experienced artists hog all the jobs.
First tho, wipe the tears, research putting together a portfolio/demo of your best work, put together a man's suit worthy of an interview, research and practice some interview questions, and APPLY with zero regard for NO NO and more NO...
Winners do that, they keep pounding on the door until someone gives them the job they want. Then, I strongly suggest getting the fuck out of your parents house.
This goes for all you 4Chan winners...and many of you could use some serious university...schooling in design and graphics hasn't killed anyone yet. lol
