What you CAN do is work on yourself. Alanon is a great place to start. Go attend a half dozen different meetings (and by that, I mean different groups, on different days and locations, not just 6 meetings of the same group). What have you got to lose?
I read an excellent post on another thread about how we all come here thinking that we are unique, that our situation is special, and that what others here say somehow doesn't apply to us. Time (sometimes more, sometimes less) tends to show us how untrue that is.
