Being ten years your senior, let me tell you, you need to be grateful for what you have achieved. I know anxiety doesn't check your resume or bank account before moving in, but know that there are millions of people out here whose goal is to attain what you already have. You're winning this rat race.
Not taking away from how you feel, not at all. I know this world is perceived subjectively by each of us, but as you can make a laundry list of all the reasons you should be satisfied, re-read that list and realize the countless people for whom good money, a degree, and home ownership are each or collectively the finish line.
I know anxiety. I deal with it every day. But were I in as secure a position as you seem to be, I'd be a lot less anxious given where I am now. I'd offer you should challenge yourself. If you're not content where you are, put yourself in a position to aim for something beyond. Clearly, you've not met your own expectations, so define those expectations and shoot for them.
