I hear you, thawing. That's a really tough place to be in. And I completely relate to having therapy twice a week and feeling it's too long in between... but feelings are what they are, and thinking that you ought not to feel this won't make it better. It's how you feel, and it's ok to feel that, I believe.
I don't have a lot of wise advice to offer about how to talk about this with your therapist... but maybe talking about why it is hard to talk about it might be one way? I think therapists are used to that, and it may feel strange or silly for us to do it in such a roundabout way, but I don't think the T will see it like that. I honestly don't think you need to worry about hurting your therapist. If she has her own issues - and which human being doesn't? - it is her responsibility to find the support she needs for herself.
Could you write down what you are thinking and send to her or show her? Even just show her what you've written here?
Thank you for reaching out here and telling us about this.
