I'm sure that email would have upset me too, and I do understand why it's upset you. I wonder if you understand why your therapist feels that she has to tip toe around you? What happens if she doesn't? If it's just because you're not ready to be pushed, then I think it would have been kinder to word it in another way. I'd prefer to know that my therapist feels the need to be gentle and patient with me as we work towards something, if that's what it takes. So personally I'd feel upset about the walking on eggshells comment because I push myself pretty hard and try my best and sometimes I just need support.

That said, I was very, very hard to help initially. I think therapists work their way forwards as they lean what best helps us in the same way we learn what best helps us. They can guide the way forwards because they've seen what helps others, but we all react so differently. My therapist definitely worked slowly towards what helped me. There were many times I didn't know what I needed. There were times when she didn't know and she told me she was stuck, she told me she didn't know what to do to help me or where to go from there. I felt awful when she said things like that. I felt like she'd given up on me and wasn't going to help me any more. The truth was that there were times when we were stuck and she didn't know how to help me or what to do. It didn't mean that she gave up on me or stopped trying...and she helped me a lot in the end.

Only you will know if you have faith in your therapist's ability to help you or if you feel she is competent enough. I've found it's been really helpful when therapists are upfront like yours has just been (now), as much as it can hurt. Sometimes it really gets things out on the table and from there you can openly discuss what hasn't helped and what needs to change and whether it's possible to find a way forwards.

Standing from a distance, it sounds like your therapist feels that every approach she's taken hasn't worked for you, however, she's willing to keep working towards finding what works (if that's what you want). You're definitely not unfixable. To me her apology sounded genuine. It sounded like she's acknowledged that many of her efforts haven't helped you and that if the thing that really didn't help this time was saying too much, then she really was sorry for not helping you by doing that.
