I think checking out other therapists can help in multiple ways -- when I checked out other therapists while seeing current T, I realized I wasn't likely to do much better (in this area) and so, back to current T I went.

When I checked out other Ts while seeing former T, I got a 'meh' feeling for the first couple, thought I could do okay-ish with one other and then felt a significantly (enough to switch) stronger 'yes' when I saw current T.

It was super painful to go through my life history in one-hour capsules but I'm glad I checked out other Ts every time I did -- if only to reinforce whatever decision I knew I needed to make.
