Well I cant give you any advice on how to break in the industry, it is very possible to learn on your own, especially nowadays.
There are a ton of books and online tutorials and videos out there. Also GameDev.net has been on spree with articles, they are a great source of info.
Then you can actually take computer science classes online for free from sites like coursera, Udacity, and EdX. Its never been easier.
Edit: I also want to add, that taking those courses can get you a certificate as well, if your into that.
