I went to a therapist who was just out of school and about 15 years younger than me. I tried to be open minded about her age for a few sessions but finally I decided I couldn't. I felt like maybe I could help her feel comfortable as a therapist. I know therapy is supposed to be for the client, but at some point any human interaction has an affect on both people, so I thought maybe it would be okay even though I felt it was partly for her. If I didn't have a choice, maybe I'd have continued to try that. She was very nice. Unfortunately now I realize she was naive in advising me to ask my gp about anti-depressants. But otherwise maybe she would have been okay. But there are therapists my age in my area, so I was able to switch since it seemed easier to do that than to deal with the age difference.
