Angry because of having to miss the trip or being treated poorly by a "codie," or because of something else? What is the primary emotion behind the anger? Use one of the Al-Anon tools on the anger. Breathe deeply. Think. Let Go.
Lonely? Get to a meeting, phone your sponsor or a member-friend, do some service work by phone or online, enjoy doing something fun with the kids or a friend, etc. Tired? Find someone who can watch the kids so you can take time to nap, rest, walk outside, read at library, do yoga, or veg as soon as possible. Get to bed early.
