I think managing this depends upon how much you know the person(s) & their unpredictability, that major events can change personality completely (especially when at a late age); especially when not knowing how they will react to a situation even after years. (& when phrasing hurting replies not intended)
Perhaps tips cannot be given universally except what you have already listed. Hope your mother recovers from the relapse and that you both can weather through future difficulties!

She still isn't doing the greatest. I've been torn. No matter how much productive things I pound at my day I still feel like I'm not doing enough or nothing I am doing is good enough. I've been to stressed out about my mom I still don't know how to navigate it. However, she keeps going into and out of hospitals :( We will see if things can get better. Thank you!
