They have reasons (A Benjamin Lasnier fanfic)

Shania was right.. I was changing, and I didn't even know it myself. Oh god why did I left her go? I noticed things just seem "off" or "wrong", I never felt hopeful or happy about anything in my life, I was becoming depressed, and why? I don't know. I noticed I've been crying for no apparent reasons,I find it a struggle to carry on a normal conversation, and I'm having troubles making simple ass decisions. Oh this is killing me, why couldn't I notice this earlier? We've broken up not to long ago, and it's all my fault. How can I just let her go so easily?!
