feelings that engulf me

I don't like these feelings.. they make me feel happy and distracted from misery but also what is important. They take over my senses and the decisions i make, most of them mistakes. I'm hoping they will disappear, but i will yearn for their presence when they are gone. They are wrong and i know it but cannot help it, they make me see this situation through pessimistic eyes. I want something new to come along therefore helping them fade from my mind.
