I don't think it's necessarily a bad thing. I've seen at least seven Ts, only two were longer term and those I was the most attached to and probably dependent on. BUT, those two were the ones who helped me grow the most. They are the reason I no longer have an eating disorder, am much better at managing anxiety and depression, and they've helped me learn how to have healthier relationships.
After a two year break from therapy, I recently started up again seeing a new T (I've moved quite a few times in my 20s or I'd see the previous long-term Ts again). I've started to tell I'm going to get attached to this one too and feeling dependent on her reassurance, but, while it does feel embarrassing, I'm not worried because I know it's part of the process for me. I've learned Ts are one source of support but have also been learning to better identify friends and family members I can rely on too.
There were some Ts I was not dependent on, but I also didn't learn much of anything from them
