Free counseling and meds won't help when you can't get someone to use them.
My SIL seems to want the counselor she sees to simply tell her she can't do anything for herself & validate her unwillingness to try doing so. When he gave her FREE meds she refused to take them. Even in the past when she has taken meds that have helped, she would stop taking them.
After a long time, you realize you just can't do much to alter the situation. Sad.
I know. I work with persistent mental illness, those who will never be cured. They cycle and are in and out of crisis centers often. And, families can't do much, except not write them off, as so many do. We are sort of baby sitters for them. They come in for breakfast, and stay all day. They have access to computers, arts & crafts, music, TV, along with other activities, as well as group sessions, which are voluntary. Maybe your sil would find some comfort in a place like this, as well as you and the family. We aren't a cure, but we are hope. And yes, it is sad, very sad.
