The thing with frustrations is that you must never bottle them up. Because the longer they stay stored, the higher the chances that they will burst out into the open and hit anyone within range. It is crucial therefore, and I mean essential for survival and building harmonious relationships, that you device healthy ways of venting out all these negativity.
Indulge in the arts. Get lost in literature. Make music. Collect stamps. It doesn't matter. Just do something. Do not let your frustrations, stresses and depressions rule your universe.
