How do you start Loving yourself?

When someone makes you feel like you're ugly, how do you find your beauty?

When someone makes you feel worthless, how do you find your worth?

When someone makes you feel like you weren't good enough, how do you know you finally are?

I didn't know how damaging falling for someone was going to be for myself. How much I would soon begin to hate myself because of one sided feelings.

I didn't know it was going to feel like this. If I did then I would have never looked in his direction...
