People are depressing because they are depressed. Not everybody lives in a little bubble of sunshine.
I didn't know I lived in a bubble of sunshine if they want to live life feeling sorry for yourself then that's their problem but things aren't always as bad as they seem
Depression is not just simply feeling sorry for yourself or caused because you feel sorry for yourself. Smh.
I've never ruined anyone's life. I think it's a bit vain to think that you affect people so much that it can make or break them. If you feel like this, you are the only person who can make your life better. So you need to work to change it.
