Just wait until you're older and the mentally ill parent disinherits you and gives it all to your equally mean sibling! Then you have what I went through. Actually like William Shatner has recently said, death can be the ultimate cleansing! I have been renewed in my father's absence. It took 10-15 years, but now I love life for the first time since I was a kid.

Hope and time...

At 21 you're ahead of the game by starting to understand it all. Good for you!
