Am I self-centered if I get upset that something doesn't work out for me?

Before I was looking forward to going outside but the weather was horrible. Why? All of a sudden? Is it just bad luck if the weather just suddenly went horrible the day my family were planning to go out? No let's go deeper..

Is it God or Satan doing this? My life has taken a dark turn with my hospitalization etc.

My parents told me I'm being selfish and I'm not thinking about how my problems effect people.

Maybe they're right? I don't know..

Also, there's a lot to this than just a bad day.
