My friend's brother has schizophrenia and bipolar and has become homeless and addicted to several things. He hasn't been in touch with her or anyone in his family for a while now but they're hoping someone might see him around London - although they're not sure how they can get him the help he needs. If you can share this around your networks it might help. I'm not sure if I could post this on any other parts of MN?
