Why do I feel depressed/sad etc?

I felt the same way for the longest time. No one wanted to date you or your friends were replacing you with new and what seemed like cooler people. I talked to my mom and started praying more and pushed myself to feel wanted because as you get older friends really don't think about how you feel. YOU THINK YOUJ FOUND SOMEONE AWESOME AND SWEET AND YOU FIND OUT HE'S JUST A JERK LIKE ALL OF THE OTHER GUYS IN THE WORLD
