If you're on any medications be sure to bring them. Try to make sure you get good sleep, traveling is stressful even if it's for a good reason. If you have a PRN (as needed) medication be sure to bring that too so that could help you when/if you're having symptoms flare up. It's great that your therapist is helping you come up with a list of coping strategies, those are very useful!

Hope your trip goes well!
