It feels like I hold two people inside me. One minute I’m calm, happy, content, headstrong, sensitive and mature; the next I become anxious, insecure, insensitive and impulsive. Also, I’m socially absent and have literally no friends. I only open up to a select one or two people and get crazy emotionally attached to them. I am an obsessive over thinker who keeps conjuring up negative scenarios in my head about anything and everything. Am I bipolar?
