Nice coincidence - my wife is also a therapist. But to get there, in my country, you need a lot of work and training, you cannot really be a 22-year old therapists. First you have to finish psychology (ages from 18 to 22), then finish Master's degree in psychology (22 to 24) and then another 6 years (24-30) for psychodynamic psychotherapy training coupled with regular therapy for yourself under a more experience advisor. And finally after that you can start calling yourself a psychotherapist.
Here at 22 you can be a psychologist, which is a different thing. They have a lot of work - intelligence tests, emotional support, advice about social stress. But they don't do therapy.
Your can become a therapist here (Minnesota in USA) with 4 years (undergraduate bachelors degree) plus 2 years Masters degree (for example, social work or marriage and family counseling).
There are - of course - higher levels of training and certification, but that gets you in front of people and diagnosing.
