I feel no sympathy and blocked an old friend who tried to kill herself. Her parents are upset with me.
Why did you block her if she was suicidal?
She would have killed herself regardless if I was there or not
You should have sympathy for people who are suicidal. Even if you don't want to be friends, you should practice compassion for others. You might regret if something happened to her.
I am trying to care about people more but it is taking baby steps for me to do it, some people are better at it than others.
Baby steps are better than nothing. Eventually you can take bigger steps even if you push yourself more. Then the world won't seem so rough on you.
