I'm sorry that you miss your mother and had her taken away from you so soon. That is really hard.

I understand how you can feel jealous of other people complaining about their mothers as it would be a reminder that you CAN'T complain about yours as she isn't there.

But don't be jealous or upset with them because their parents are there taking part in their lives. Just because they're there, doesn't mean that it's a good relationship. If I ever had kids, my mom would be RIGHT in there trying to raise them... and I know that she would not have any respect for my parenting style or boundaries. Other people would probably view her as fantastic, but for me, it would just be a continuation of the way I was treated growing up, combined with the likely exposure of my children to me being disrespected. While she would look on the outside to be an absolutely great mother... she isn't.

Not everyone you hear complaining about their mom's are doing so without reason. A lot of them probably have very valid reasons for it, and it's ok to mourn your own mom when you hear their complaints. Just try not to be resentful for them. Some of us would be grateful to have had even ten years of having a good mother, instead of the many many years that we've had with mothers who make our lives a lot more difficult.
