I think it's perfectly normal to be angry at the world when you are suffering.
I also blame some hostility on medications..but really, it's killing you that you have been robbed of your health....
I get madly jealous of my colleagues at school or girls on the street. they don't have to deal with nerve pain and sexual dysfunction. I have had to give up my dream of ever getting married have children..at 26 years old.
So yeah, I am very angry. I just hope I don't stab someone
