Depressed little sister?

first of all this is a serious, but it should be acted upon as if it's something simple. let her know she means alot to you, but dont make her feel like shes interrupting your life, that will only make her feel like more of a problem. spend more time with her, this could just be a cry for love. theres nothing cooler than being the girl with a big sister whos fun. take her out , introduce her to a few friends even though it may seem embarassing, shell be greatful you did. let her be a part of your life. and slowly shell learn to socialize better. do her make up just have a few girls nights and enjoy eachothers company, itll benefit you as much in the long run. all she wants to know is that she matters.
