Trust me being alone is better than being in a relationship with some jerk.
Also, things can always be worse - trust me. If simply being alone is the only thing that's got you down right now, then count your blessings and feel lucky.
Also know that most people in this world are NOT in relationships. More people aren't in them than are in them. So you're a part of the majority, not the minority, so how can you truly be alone when in the majority, but you're in the majority for being alone, and oh god
