I don't think about suicide, but when my wife asks "aren't you sad you will die one day? . I'm like "no, sad for the kids, but I will be dead, I won't know and I won't have to work in the morning--So that Seems fine."
I hate things like North America is supporting Israel and so many kids are dying because Premiers and Presidents aren't stepping in. It makes me weary, but I try to do small things to make other peoples lives better.
Sometimes that has been making homemade bread and soup to hand out to homeless peopl. Sometimes its seeing a craigslist ad of somebody getting rid of something they think is broken, and I'll respond with instructions on how it can be saved. The happy replies when you just saved somebody a $350+ repair bill (or cost of rebuying something) are worth it.
