You really have had a lot to deal with but I think you are doing magnificently well considering all the stress and mourning you have gone through. Things will settle back down and this soon will be a bad memory. I'll be praying that everything goes well with your Mom. It's good they found the blood clots. There is medication that can break up some blood clots so I hope that's all she will have to do.
Just take one day at a time and you will come out on the other side of this.
