I'm doing well enough. My sibs were closer to her than I (physically and emotionally), but it's still hard to deal with the fact that she's gone -- better today than yesterday, but it's not something you ever completely get over.
Dad died about 15 years ago, and that is sometimes hard to deal with too, but I do deal with it, have my moment, and move on.
Thank you all for your condolences.
