Rather then seek a spell for them, I suggest you learn how to deal with them accordingly.
If your feelings are negative and leading to destructive tasks or results or anything like that, you should probably get a therapist or councilor. Writing poetry, drawing, painting, and other arts can also help you to express and then overcome such emotions.
If your feelings are positive and leading to productive tasks or results, I really don't see anything to worry about.
If you just want to stop feeling entirely, that is foolish. Emotions are a large part of what makes us who we are. We just have to learn to deal with them.
