I've only ever had one therapist and didn't shop around speaking to others on the phone etc. I went to see her the first time and knew I wanted to see her again. The first few months was a lot about us building our relationship with me deciding whether I thought she was credible, whether I felt comfortable with her (which was difficult to decide for a while because because the whole idea of therapy and the process of talking about myself was very uncomfortable - but I realised that the discomfort wasn't to do with her) whether I really trusted her etc.
I've now been seeing her for a year and our relationship has really developed and she is really important to me. My discomfort around the whole therapy process is still very much there - I still hate sitting there talking about how I feel. But she tries to make it as comfortable as she can – she's very intuitive and will discreetly make adjustments to herself/the space/how we're working try to give me what I need. We're both very honest with each other and talk very openly about what's going on in our relationship/our energy/the space and I think that really helps.
I've recently posted elsewhere that my relationship with her feels a bit rocky at the moment, just because of how I'm feeling and how I'm reacting to those feelings. But even though it feels rocky and uncomfortable, I hasn't crossed my mind not to see her. And I know part of the answer is that I need to talk to her about what's going on. And, uncomfortable as that may be, I'm pretty sure I'll feel much better after discussing it with her and that conversation will probably strengthen our relationship further.
I feel very lucky to have her because I know I wouldn't have gone to some of the places we've gone to if it had been with someone else who didn't feel so 'right'.
