If your doctor is sending people around then it sounds like he is concerned. They might just want to come around for a chat, maybe assess what the situation is like. Maybe let you know about the help that is in your area.

IF they do suggest hospital it may be on a voluntary basis. Clearly you do need some form of help. If it does turn into hospital, it might not be such a bad thing for you to get concentrated help.

Hospital is not a forever thing. People have voices in their head for lots of reasons. Just take each day at a time and accept help.
