I found my therapist through https://www.bacp.co.uk/ — I’m not sure which country you’re in, but there’s bound to be similar directories out there.
I set their filters to find therapists who deal with issues relevant to me, and within a practical distance. After that, I just systematically went through each of their profiles, read their bios, and narrowed it down to a shortlist of 10.
I then picked two based on gut instinct. I had an introductory session with them both, and immediately “clicked” with one of them, who I’ve been seeing ever since.
My therapist works specifically in “Person-centered therapy”: https://www.psychologytoday.com/gb/therapy-types/person-cent...
I'd recommend searching "psychotherapist" or "psychologist". Psychiatrists seem to be more focused on prescribing medication than helping you work through your issues.
