Wouldn't people wonder what you were smiling about... If you stopped reacting negatively and started believing things will get better and rise above their petty taunts? They would get nastier at first, in an attempt to get you to react. But eventually they would leave you alone. You have the power to be that strong, anything is possible with Jesus!
Self love is so important. Because when you're all alone and it's 3 in the morning and you're lying on the floor crying and shaking and wishing it all would end, who's going to be there for you? You. You have to pick yourself up and find the strength to carry on. At the end of the day, you're all you've got.
