I see. I missed the part that the scheduling would be online - that is pretty convenient! Just to find some silver lining: maybe it could even be an advantage regarding your grief that you could spontaneously check and see if he has an open appointment when you have a particularly difficult day/period, rather than having to wait for the upcoming weekly session? That kind of arrangement would have been nice for me, for example, when I was freshly sober and struggling with frequent and intense temptations to pick up the habit, or during the time when my father was declining toward the end of his life and I was very anxious because I never knew what news I would get and when. Those were priority issues for me back then, over work or anything, and it would have been helpful to talk to my T when I needed, not when a standing appointment came up. I do believe that working on self-esteem is probably better done on a regular, predictable way that can turn into a routine, including the ability to wait and remain relatively calm during challenges (that ability, by itself, can boost a sense of self worth, IMO).

As for "clicking" with a T, in my view that does not necessarily need to involve emotional bonding, I see it more as compatibility of personalities and approaches. For example, that you find the T's modality and style appealing or at least tolerable, and it can be helpful for what you want. I personally don't mind a certain level of bonding with a T and enjoy the connection without its becoming excessive/disruptive, but I can't work with someone I do not click reasonably well with - that is, I do not disagree with their methods and our communication styles are compatible. So there are nuances, I think.
