If people insult me and hurt my feelings, I usually just let it slide. I am so used to it after hearing everything bad about myself for so many years. I keep saying I will take a stand, to not let them treat me that way, but I get scared. It's weird, it's like I don't want anyone to be upset with me, to offend them or to make them angry with me, even though they obviously don't care if they do the same to me. How do I stop worrying about things like that and just speak my mind?
