Being called ugly and fat when you’re younger really affects you later in life. Anytime someone tells you you’re attractive your heart drops waiting for them to say they were just joking or following it up with a hurtful comment.
“Let go of the past” is not productive. Because self-reflection is key to growth and healing. There is no moving forward without it.
Examine the past. Understand how it affected you. Isolate disordered thought processes and consciously alter your inner narrative to yield better results.
But never let go of the past. Make the past let go of you.
