Anger takes energy. the problem is that I personally think that the anger is better for you, but harder on everyone else, especially if the anger is sortof generalized and you can't find the proper focus for it. It could be that you don't have the energy right now to maintain the anger. Go easy on yourself. I know that the language situation in the southland is a real pain if you don't do spanish (we had an incident with our oldest son at a daycare where the only person who would talk to us about an accident was a 16 yr old illegal who couldn't speak English but wastrying to alert us to a possible concussion, Yikes!) Do you know anyone at all who can go with you who can at least understand?
I really hope that you can get that problem solves. Hang in there, and be kind to yourself, though it's hard to do when you feel like this. Huggs.
