Steph,

The meds which your father is getting help cure the body. The side affects changes the mental well being. My father-in-law had terrific mood swings where we didn't know what to expect from one day to the next. Many nights my wife would come home from the hospital just beside herself. My wife is a nurse and is very aware of what these drugs do, but it was still her father and she had to endure about the same type of behavour that you are going through.

Strong people can only endure so much before you reach a limit. Yell! Scream! Find what will work for you to relieve the pressure. Come to the site and vent as much as you want. You can't keep all of that inside without harming yourself. We will listen. That's what friends are for. If you need something just ask.

Hang tough.
