This is what I am. I have periods of enormous self-destructive depression, where I go completely off my trolley and lose all sight of reality and reason.
Basically, the reason I'm vegan is because when I was about 16 or 17 years old, I began to understand that we don't need to contribute to the killing and exploitation of animals to feed our bodies correctly.
I associate going to an airport with work because I travel so much with my job. So when I have a few days free from work, I tend to stay at home.
