feeling too much gets exhausting after a while

When emotions get the best of you, you're basically screwed.

They are mercilessly powerful, and are easily evoked. They make you irrational. They stupefy you, curbing your capability to think sensibly. They obscure logic. Some people are slaves to them, propelled to extremes, their perspectives and actions driven entirely by emotions.

Then again, without them, we lose our humanity. Emotions exist as a sign that we live for something. Positive ones make us feel good about ourselves, bitter ones, more often than not, help us to realize what truly matters to us. Disappointment, regret, jealousy and all their sore cousins.

Sadly, we can't happily decide the circumstances in which they are allowed to overwhelm us with their presence, or when they choose to manifest themselves as they grandiosely announce their arrival. (Unless you're in complete control of your emotions, then good for you.) Nor can we predict the extent to which they may engulf every fibre of our being, or how long they will prolong their stay. They strike unexpectedly in relentless waves at the most inopportune of times, leaving us crippled over by their gravity.

Which is why, a switch like the one above would be convenient. Really convenient.
