so today I found out that a girl I like is dating someone. I'm going to be complete honest and point out that I have oneitis towards her. After having a breakdown and feeling like shit I have no idea what to do next.

How should I treat myself in a positive way to value myself, respect myself and become emotionally free? I honestly want to stop this cycle of straight up shit and illusions. But just thinking about it is a punch in the face tbh.
