The problem with the 'I just suck it up" line is that they DON'T just suck it up when they get depressed or angry or anything else. They take it out on the family. But then according to my dad, mental illness didn't exist. People made choices on how they behaved or reacted to things. His "advice" on the bullying I was subjected to? "Just don't let it worry you".
Really helpful, Mr. 2 or 3 college degrees.....
