i also feel like something dark is trying to consume me and yes it's mainly before i decide to go to sleep at night! you say you were once happy! i'm only 18 and i don't think i've really truly been happy. my mom is the only one who holds the key to my happiness because she's the only one who made me feel happy. but my dad and step-mom! used her as a punishment against me. in the times i needed my mom i couldn't have her but even now as an adult i still feel that same pain and including everything els!
