Get trained with some.
There is a massively growing demand for therapists. World events and changing culture are creating the conditions for widespread personal crises. This has a big effect on the economy and is really an underlying root cause problem for many other visible socio-economic problems. Science now strongly backs modern psychotherapeutic practice, and it can be a rewarding career.
Most (good) training is the usual 3-5 year programme involving psychology, reflective practice, clinical work, self-therapy, clinical supervision. You can choose amongst a range of different "schools" (cognitive, behavioural, attachment...) which are increasingly combined and regulated by the same bodies.
It;s also hard work to be a professional. For the good programmes selection is actually tough. Would you be able to help people traumatised by witnessing horror? Rape victims? Or neurotic, obsessive patients who break boundaries and call you at 3am? Can you keep absolute compartmentalised discretion on par with doing intelligence work?
Good luck.
