Speak up;

“Confronting our feelings and giving them appropriate expression always takes strength, not weakness. It takes strength to acknowledge our anger, and sometimes more strength yet to curb the aggressive urges anger may bring and to channel them into nonviolent outlets. It takes strength to face our sadness and to grieve and to let our grief and our anger flow in tears when they need to. It takes strength to talk about our feelings and to reach out for help and comfort when we need it.” 
― Fred Rogers

Sometimes people need to know that they have hurt you even though in the process of telling them, you may be hurting them. Otherwise, they will never know what they have done wrong. There are times you need to be fair to yourself, just like how you are fair to others. You cannot please everyone and end up not being fair to yourself. Now that's called not loving yourself and loving yourself is equally important as loving others.
