I had a period of seeing a therapist last year. To be honest, I didn't really get anything out of the experience.
It's not really just the discussing of personal issues that I found difficult, it was the fact that I was expected to do it on a certain day at a certain time. Sometimes, on the day of my appointment, I just didn't want to talk. At other times I felt that I couldn't really care less about my problems.
What I needed then was someone to talk to in the "heat of the moment" when I was vulnerable and upset. Those are the times I could have opened up.
I also resented the fact that I was expected to make a financial contribution. Though it wasn't expensive, it just made it feel like "emotional prostitution". By that, I mean paying someone to care. Paying someone to listen. I really needed a friend at that time, someone who I knew would do it because they cared. Not because they were being paid to.
