So recently I've been going through some anxiety, which can sometimes lead me to feel depressed. Right now I'm feeling depressed over something from nearly a year ago. A stupid joke I made about something, and it's only on hindsight I realise how insensitive of me it was to make a joke. I mean, people died for gods sake. It wasn't directed at the victims, but rather at someone I dislike being the cause. I don't feel guilt towards that person, because I still strongly dislike them, but it was still insensitive of me to make a joke, and now I feel horrible about it. How do I get over it, because I feel miserable about the whole thing
