I agree! Spelling isn't important---it's what you have to say that is important!
You feel dumb? But you had no way of knowing what was going on with T so be kind to you

I'm glad she called too and while it is nice to get some extra time if needed, if T knows this about a particular client, maybe she should be keeping her eye on the time and her client's state so they can do what they need to do to stay in the allotted time. I agree with earthmama's suggestion to talk about this and ask how likely it is to have happen. Maybe you could ask to not be scheduled after this particular client, if running past the allotted time happens often with this person.
Yes, trying is hard, and especially hard when we aren't feeling great
But it's the only way forward so I hope you'll keep posting and keep trying
