Needing Supervision

My GF has bipolar, she has her medication which she takes, most of the time. She will go and see her GP when she has to, she’ll have her blood tested, and she has kept almost all of her appointments with her consultant

However, she point blanks refuses to have a social worker, won’t have a Community mental nurse about the place in other words nothing but medication

Can I use this fact as part of an effort to show that she does indeed need supervision. Is there any particular point I should point out

Many thanks
Kevin
