Hi SadNEmpty, I can imagine it must be quite a loss for you to have her leave, I'm sorry
But you know the fact that she really "saw" you does say as much about you too........the fact that you opened up to her, let her in, let her "see" you.
Now I know that all that may be really hard to do again with a new T at first, and it is probably going to take time, but hopefully they are going to be as experienced, as supportive in helping you do that........and from their experience and understanding as skilled at "seeing" you.
And you know, you can help them with that too by telling them some of the things your T did/some of the things you did together that helped/that felt important to you.
I know that probably doesn't help much with the sense of loss you probably have right now but maybe use some time to reflect back on some of the important aspects of your sessions, the progress you made, what you gained from your T/from the sessions and try to hold on to all of that.........and of course your internal "safe place"
It's completely understandable that you'll have a sense of sadness but try to take with you/keep the sense of "good"/"fulfilling" things that came from her/your sessions too, hey??
