I miss you dad

I am having a hell of a time with the estate. My dad had a lot of investments and he sold a lot of stock but the problem is everything was sold after his date of death. They did a trace on the paperwork which was also sent after the date of death, however it did have his signature. They have never encountered a problem like this before and trying to sift through the legalities have been tough to say the least. We're pretty much going back to square one. I just miss him so much. I wish I didn't have to do any of this. I wish he was here. I would give anything to see him again. I hate dealing with the estate, and creditors, and it seems no matter how much of it I get done or sift through there comes along some problem that makes is so you have to redo everything all over again. And frankly, it is not fun to deal with your parent's finances. And I know a little about investing and retirement accounts but only basic, standard knowledge and my dad was great at it and did everything himself. There was no broker, so it makes it even harder to try and track everything down and get it taken care of. And there's something so hard about just dealing with his estate itself. It makes me miss him so much and it really hits home that he's gone.
