I can relate to how you feel I found my last T’s account on a social media and scrolled through about 5 years worth of posts. I found out a lot of stuff about him and his family.
I didn’t tell him for a year as I was terrified he was terminate and I was so ashamed. But eventually I knew that what I was reading was negatively influencing my parental transference towards him, so I plucked up the courage and admitted I’d been stalking his page. I was a sobbing wreck and he simply said ‘If you think I’m angry with you, then I’m absolutely not. If you feel guilty then there is no need. All I would say at the moment is that clearly this is not something that is helping you so it might be best not to look at it again, but that isn’t me telling you not to, and I certainly won’t be angry if you do, it’s just me wanting us to have the best chance of helping you.’
In the end I asked him to block me, which he did and we had some really useful conversations about things that I had seen on there and how they made me feel.
He also made it clear that it was his responsibility to think about the fact that there is always going to be the chance his clients will come across his account and that it’s for him to manage and only put things on there he is comfortable with them knowing. And I think that’s an important point for you to remember with your situation.
