Can Somebody Help Me?

Today has been a pretty crappy week. In general, life has been pretty sucky lately. My younger sister has a new boy freind and I feel so jealous of her. I know this is horrible, but I cant help it. She is my best friend and I dont even fell like we can connect anymore because she is so obsessed with him. I really want a boy friend. Life as a homeschooler is the loneliest life I have ever felt. I am very depressed right now. I would appreciate anything you guys could tell me to cheer me up. I know this is a little desperate, but I could really use a friend right now and this is the only place for me to go.
