I think it depends on the arrangements you made with your T about his vacation. Did he say to contact him if something came up and you needed to talk? I think some T's would want to be on their vacation and have emergencies taken care of by whoever they arrange to do that in their absence. Because it is hard if an emergency comes up for the T to deal with it long distance. And plus they do deserve a vacation. Do you think this is an emergency? I can tell it is certainly very important to you. I think even if a T would normally be fine with a client's call about an important matter if he was not on vacation, when they go away on vacation the "rules" change a bit and they expect the "on call" therapist to handle urgent inquiries. Would it help you to speak with the "on call" therapist?

I think the journaling is a good idea, but if you keep journaling about the same topic, it can also just serve to keep it foremost in your mind, and maybe that isn't that useful now since your T isn't available to help. Maybe you need some distraction from the topic instead of dwelling on it. I find that getting a lot of physical activity can be really helpful in this type of situation. Gets your mind off the issue. Gets the endorphins going. Gives you a sense of accomplishment when you complete your workout. Etc. I wore myself out yesterday mowing the lawn of my very hilly yard and then raking up all the grass. Took a couple of hours. I was exhausted but felt really good, and it was so much effort that I couldn't think of anything troubling at the same time.
