> if you're unhappy in a profession at 22, you will not be happier if you waste even more years chasing down a blind alley

Can't agree more. I changed from theoretical physics to CS upon realizing that a) it's not my true calling and b) I'm not cut out for the highly competitive research community ("publish or perish " etc.), coincidentally also at age 22.

Found a well-paying developer position within a few weeks, and my employer allowed me to work part-time and do a CS bachelor in parallel. I just finished that, and I'm very happy with my choice.

What I'd recommend is that you seek some in-person counselling (unis usually offer career advice counseling to their students) and talk it through thoroughly.
