I'm sorry you're not doing well, growlithing. I'm in a similar situation, and I know how hard it is. I'm struggling, too.

The only thing I can offer is that your therapist is trained, and since the break is planned, most likely is familiar with the possible reactions of her clients. I have no doubt she will not be disappointed in you, unless you do something harmful to yourself. Losing that emotional anchor point can be really unsettling, and that's a long time to wait. Hang in there, and try not to pile on by blaming yourself for your pain.
