this must be very difficult for you

ugh.......
I so wish you could have a "do over" and would have written all those lovely things down and given it to her face-2-face to read with you sitting right there..... then you would have had her undivided attention. I would bet my life on it that she would have said some very gratifying comments to you.
Some people, I believe, just aren't very good at email.

the absence of the physical can seem to cause some to react with distance..... for some reason

I can sure understand your feeling dissed.
but I also understand your T. being in business mode away from the session..... especially with a sister in the hospital... she must have been so worried for her sister.

I wish though your T. would have said in her phone message how she appreciated your sentiments.... but you know what...... I don't think there is a person alive that is perfect... every single person will not meet our expectations all the time..... I imagine now you are thinking-- "but she knows me and she is a professional therapist-- she should have known what I needed"....... perhaps.... but again.... not a human alive is perfect. dissappointments will be part of it.... it's how we overcome/cope with those dissappointments that is the key.
best to you
