Have you asked her for ideas on how to cope during the week (ie. mindfulness, writing)?
What is the t's reason for keeping sessions to every other week and not increasing?
Can you ask your t what her out of session contact rules are? Maybe you could send her an email once or twice during the two weeks off to help you process some of your feelings. If you find email is allowed, ask if you will get a response so you know what and what not to expect.
