I do all the time. It's getting worse recently and I'm starting to think it's not normal for me to feel like this.
Whenever I notice I'm laughing or enjoying myself I start to feel guilty as there are many people in the world suffering and I think why should I be happy?
Yesterday I had a moment where I felt excited for Christmas, then I thought how can I be happy when this bad thing is happening or this person is sad or having a bad time.
How normal is it to think like this?
