Therapy is more about talking to yourself anyway. A therapists job generally isn’t to give you the answers, but help lead you down the right path.
If you have serious issues get an actual professional, but if you’re mostly just trying to process things and understand yourself or a situation better, it’s not bad.
I assumed you had 2 points, the self hosting point about what you’re saying now, and
about its ability to be a good therapist or not in general. I was responding to that. Sorry if I misunderstood.
