Do not feel pressured that everyone is in a relationship already. It's not a competition. It's not a race. Do not force a relationship to happen. Do not settle for less just to have one.
True love comes to those who wait. There's no need to rush. Love when you're ready not because you're just envious of your friends.
Do not feel bad about yourself. Someday, someone will love your wholeness. Someone will treat you like you're one of the best things that happened to him. For now, chase your dreams and be a better person.
