Some feelings feel particularly heavy, and no one likes that. Having been on both ends of the coping spectrum, i.e. letting negativity overstay its welcome, versus not acknowledging its presence at all -- I share why it is necessary to find a balance between the two. You're already feeling the ick whether or not you want to, and choosing not to feel it now, is simply postponing it. Letting it through is the fastest, cleanest way for it to leave.
