I'm in a similar situation. My T is super busy too but I still get to see her once a week in term time as she puts students on a waiting list if she can't fit them in.
I'm just coming to the end of a three week break and I've really struggled so i understand what you're going through.
I've written a lot of things down for my T, some I'll send in an email when she's back at work, others helped to just get it out.
