Could this be depression?

It's tough, thinking your alone. I feel the same way. Things will get better over time, that's a promise. You'll meet new people to be better friends and you'll meet a new guy who treats you the way you deserve to be treated. It might take time but just know that it will come. Right now just focus on making yourself happy, doing whatever you feel is the right thing for you to do. Spoil yourself, and dance to your favorite music when your alone, lol no joke it works.
