I suggest you get a new therapist, or at the least, give this letter to the one you have. I wouldn't expect a gift exchange, and I tried to explain why not in the other thread you started, but I think her mentioning she might save you a matzo ball and then not, and being too busy for you gives you *justifiable* feelings of being unworthy.
Other therapists are more open to what you want, if it's worth pursuing to you.
Also though, I hear you needing help in the moment with crises. Some therapists can be there- mine often can which is amazing, but a lot can't, or even if they want to, the timing doesn't work out. I wonder if you'd consider DBT which is a form of therapy focusing on emotional regulation to help those crises seem more manageable, to help you get through waves of emotion. I'm incorporating it into my therapy with a workbook and discussions/brainstorming with my therapist and it helps me have a sense of control, of being able to take the edge off my intense emotions when it's not practical to work them through therapeutically.
Good luck, I'm sorry you're struggling so.
(P.S. Just saw the word DBT in your post, not sure how far in you are, but I have found it helpful. Reading your post again really does make me lean toward having you find a more nurturing therapist though, I am sooooooooo relieved and happy to have found mine after more clinical/detached/incompetent ones when I was younger.)
