Hey,

it sounds like you are very respectful his time and the boundaries of therapy and under normal circumstances you would not contact him at the weekend, but this isn't the normal circumstances and I think if your feeling very SUI then you should call him. He will know you don't do this all the time and that it's important. Therapist's know that calls out of office hours is part of their job, like a doctor on call almost. If you didn't call him, he may wonder why you felt you couldn't when your in so much need of support. You have an extremely valid reason to call. In fact if you can't call your T when your feeling SUI, then when can you?

*huge hugs* I have been SUI many times in my life so I do understand
