There was definitely a time in my younger years where I bore a bit of a grudge against my parents, and especially against my mom but I am long past that.

As you said, they went through their own periods of hard times and those were very different times from what we experience today. I know they did the best they could with what they had and I'm grateful for the knowledge they passed along, even though there were also some years of therapy to get over the negative parts!
