my mom just got diagnosed yesterday

please give me any advice you can. my mom (she has been through more than anyone i know, and she recently left a job because it was impacting her well-being) and just got diagnosed with an aortic aneurysm and stomach ulcer within the past few days. i have researched it a far bit when i’ve gotten the chance too and i won’t lie everything i’ve seen hasn’t given me peace at all. i just want to hear from the people who experience it, what will she go through in trying to heal from this, what while she experience, how can i help her best? please be honest. i don’t care if it’s hard to hear. even dietary, exercise/resting/yoga/idec i’ll make her vegan and gluten free if that’s what it takes
