You could consider talking more about what you are interested in, what makes you happy, and less about the problems with your current situation. If you have even a little bit of energy that you can put towards something which you care about more than what you're working on now, you can start to move your life in a new direction. Eventually you'll start to take some risks that you are not brave enough to take now, but you need to be positive. Don't worry about making drastic changes now, they can come when you're ready.

Complex problems are good if you care about them. A smart person working on it is a good sign. You just need to find a small way to contribute or even just to learn, you don't need to take over the world. Just do one small thing towards finding what you care about.

In short, don't worry about changing your current routine and job, try to find something you really care about and work more on that in your free time. Trust your gut.
