"...the languages that I know are limited to vb.net and c#. These are not exactly high level languages themselves..." Not only are these very good high level languages but there is lots of well paying and reasonably easy to get work around for competent users. You sound a little overwhelmed which is normal, confidence is only going to come with experience. Whether or not you decide to study formally, write a lot of different code in your own time. Imagine big problems, then break them down into smaller simpler problems that you can actually solve. Building Facebook must feel like an impossible task right now, but I bet you could build a database to store a list of friends. The more you do this the more you'll find 'big' problems are suddenly easier to understand.
