I want to try and do as much as i can to not burden my family so if i have the time, energy and motivation (not sure that i have any of those left) i would want to pack up my stuff, designate what can be donated and where (less research for them), put aside things they may want that are sentimental, and create a document of stuff they need to know like preferred burial plans, a will if possible and put aside clothes that they can choose for the funeral. The less they have to think about and do the better, its the least i can do since i know i will be hurting them. Writing letters i'm still unsure who i would write to specifically, struggling with that.
