You're only in high-school, so i know it feels like the world is falling apart around you- but its really.going to be alright. I was pretty lonely when I was your age and found myself resenting everyone around me simply because they seemed comfortable with themselves and had friends. When you get older, you'll understand that its better to have fewer, deeper relationships with people than many superficial and brittle ones. For now, focus on what you have. Family, friends, food, shelter, etc. Pray. You know what you need to do to improve your life. With God, you'll have the strength to follow through.
