Trusting or loving yourself is not bad, really, not at all. It’s not that you are being selfish or self-centered. You are trusting yourself aka you have faith in yourself. Love yourself. Be who you are and not what others want you to be and trust yourself. At least it’s far better than trusting someone else.
And lastly, be strong enough to not to depend on others when you fall to pick you up. It’s you who has to stand on your own without any support.
Remember, “you fall alone and you stand alone. You fight alone and you fly alone. You stay in the darkness and cry alone so why do you need someone to help you go on? Be your own knight, be your own king, be your own judge. No one’s better than you.”
