This is excellent advice. This, this, a thousand times this.It's an incomparable loss.
I can only hope that you don't feel under pressure to adapt at anyone's pace but your own.
@Warped9 it sounds like you took care of all of the important stuff and like you said, you made her feel like she mattered. That’s tremendous. I know it may be hard to see this right now, but you will be so glad that you did all of this six months, a year, five years from now, whenever. Yes, you are feeling some relief now. DO NOT FEEL GUILTY ABOUT THAT. You have been through a marathon ordeal. Of course you are now feeling some relief.
Relatively speaking, I cannot imagine there is much urgency now for any of the remaining things that need to be taken care of. Feel free to accept help from trusted friends and family members if offered, and take it at your own pace. You’ve done a hard, wonderful thing.
