How best to support someone with a new diagnosis?

Hello everyone! I hope you’re all well. My SO was diagnosed this week (doc is quite certain it’s type 2). So it’s been a whirlwind week of new information and lifestyle changes and ‘do this do that’. We’re both quite overwhelmed. So far we’re taking it day by day, but I wanted to ask you all: when you were first diagnosed, what did you want/need in terms of support from your loved ones? And going forward, what are some of the best ways that your loved ones have helped or supported you on this journey? I want to do everything I can to help my SO into this new chapter of our lives.
