A stable source of income is nice, but that means something different for everyone. I get the feeling you would only be satisfied with something in the six figures range, but I truly believe that you can have all the happiness you want with a modest income or modest whatever.

A T can help with these things because the amount of self-hate and criticism you have has to have come from somewhere and started for a reason. A T can't help you be better at your career necessarily or stop others from being better than you, but they could help you deal with the pressure.
