Hello RosieGamgee: I'm not the person you're looking for here on PC. However I noticed this is your first post. So I thought I would at least welcome you to Psych Central.

Here's a link to the Bipolar forum, here on PC, just in case you haven't already found it:

And then here are links to 5 articles, from Psych Central's archives, that may be of interest. The last 4 are targeted more toward family members of people who have bipolar disorder. Hopefully though some of the suggestions in them will still be of help:
