Dealing with Negative Comments About My Appearance

I feel so demotivated right now. I've been listening to subliminals for years, and I genuinely feel like I've improved and become so much more beautiful. But today, my mom came to me and said that my lips, eyes, and nose are so ugly and that I'm not beautiful at all. Hearing those words from her hurt so much, and I felt like crying.

In my mind, I keep repeating to myself, "I'm not ugly," but now I'm questioning everything. Does everyone think the same way about me? Am I being delusional for thinking and feeling that I'm pretty?
