How is it possible for me to be so happy yet so sad at the same time?
Literally I have the most perfect boyf a loving family... everything a girl could need and get I often catch myself feeling really down and I can never really put a finger on what's getting me down and then it frustrates me and I get even more upset and ugh it's just weird.... don't get how I'm still so down when my life is so good.... 😭
