Few days are meant to be spent laying alone on your bed for the most of it, gazing endlessly into nowhere and giving time to those thoughts running all over your mind. This time spent is like the mirror, that reflects everything that's going on in your life.
Cry that pain out, no one’s judging; laugh on the silliest of things, no one’s judging; invent mind palaces, wear crowns and be its ruler, no one’s judging; stuff as much food as you want in your mouth, no one’s judging. "Alone" comes as a necessity sometimes. Staying alone gives you the sense of realisation that you can live well, and make it on your own too. It gives you an escape.
Don't be afraid of spending time alone, of eating alone, it just means you're comfortable enough in your own skin and don't lack that love that most people keep searching for in others.
