Sorry I couldn't get to this earlier.... As far as what you might be able to do to work on GAL: You are a horse person, so how about looking into helping these folks: Cloud Dancers
Also, I couldn't find any specifics, but there must be a horse rescue organization somewhere in the area.
Right now it seems to me that you should support your family and let them support you. The situation with your wife can take a bti of a backseat for now, call it detachment. You need to be concentrating your energy as positively as possible, and build yourself back up.
