You never really work for yourself (unless you're a self-sustaining farmer) - you work for clients/users, and they can be even more fickle than the corporate overlords.
I just left a corporate job in London at a Fortune 25 company that paid 78,800 GBP a year and moved to a different country with a smaller / lesser pay. I did it because I wasn't happy with the corporate life.
Don't measure your life by the size of your paycheck. Think about what you want to do and just take a leap of faith. If you choose to stay on, then invest some time and learn a few more programming languages and get some domain specific knowledge. If you don't have a specialization then that could be your start.
