I don't believe it is easy to know what you want to do with your life at any age. I've always felt you make a decision based on what you know now and adjust until you find something that feels right. For me, my work aspirations have changed as I changed. I think a little differently today than I did at 29.

It is fantastic that you found work you love. It would be good to reflect on what you love about it and try to determine if any of the opportunities you see before you will have the same characteristics that you love. Loving your work is a huge plus...especially, with living with anxiety and depression.
