I Am Constantly Torn Between Logic And Emotion

It is quite amusing how I can go from an amazing day, to an extremely low point. Probably the lowest I've been in awhile. My thoughts are controlling me right now, I can only hear three voices and all three are telling me terrible things about myself, and others. I feel as though my time being in a euphoria is going to end, and that I'm going to somehow hurt someone I love. I feel it, and the voices in my head tell me I am. I will try my fcking best to avoid it. I refuse to lose someone I love and care about, yet the voices in my mind want me to part ways. I have been tormented by my thoughts, I hate this. I just want them to shut the fck up and let me live peacefully. I want to live my life with the one I love.
