Hey man, I'm sorry your mom and you guys had to go through all of that. I think I can understand to some extent.
I've found myself in a few situations myself where I was doing something for people out of love and all they could see was me sabotaging them or hating on them. Like you, I still kept on, in hopes that they see my intentions for good. In some cases, they have, but sometimes even when they don't I become the bad guy and I carry on. Constructive criticism of loved ones for instance is mostly not greeted with open arms, but what can we do?
At the end knowing that love will always win no matter what. As long as the love is true, winning is inevitable. But then again love doesn't even think about winning, it just wants peace
