very interesting topic!

To me, depression never allowed me to get where I wanted to be, professionally. I started studying to be a lawyer when I got into a difficult time and had to leave it on hold. Many years have passed, and although I work a lot and pay my bills, I want to be satisfied and have a career that would make me truly happy. I just returned to school to study Psychology and I don't know what will be the outcome of someone who endured a mood disorder for so long to perform in the same field professionally, but I have this deep urge and passion to help others with my own experience and soon with academic knowledge. I'm aware that it won't bring me a desirable financial return and I may even make less money than what I do now (at least in the first years), but at this point in life happiness and emotional stability (that I hope to achieve with it) is way more important than anything else, because without it I'm not sure for how long I'm going to be able to cope.

Furthermore, I believe that you should follow your heart, but carefully. Be very certain of your possibilities and If it fits both your passion fulfillment and your financial needs. You can always research and slowly study this move. I support your decision if that will bring you happiness, although nothing is perfect. Don't let the rocks in this path discourage you.
Be well.
