Hi DLSH, welcome
Your mum is on track doing many of the basics we have found to be effective.
The problem is that many of these rituals work over time, medium and long range not necessarily short term fixes.
Your mums issues seem to be on the more extreme side. This means patience is needed by others. Medication and other ideas might be the early noticable changes short term, hopefully.
Meds will cause side effects. In my experience at least 8 weeks is needed before one can feel any real effect. I tried 12 before one hit the mark!
We arent professional medical staff so you are reading experiences of those who have been there.
The best thing I can do therefore is list several threads pertaining to your mums issues and that of her lived ones. So, use google and select ideas from these threads you havent tried. You only need to read the first post of each thread if you want.

That is a sample. Up the top of the page youll see "all posts". Under various sections you'll find posts you can click onto.
Its great you are so concerned for your mother. A bit more education all round and patience might turn things around.
