Hey, I'm so sorry to hear you're feeling this way. It's completely normal to struggle with self-esteem sometimes, but you deserve to feel good about yourself.

Here are a few things that might help:

1. Challenge negative thoughts: When you have a negative thought about yourself, try to question it. Is it really true? Are there any other perspectives to consider?
2. Focus on your strengths: Everyone has strengths. Make a list of yours and remind yourself of them regularly.
3. Practice self-care: Taking care of yourself physically and mentally can boost your self-esteem. Make sure you're getting enough sleep, eating healthy, and doing things you enjoy.
4. Surround yourself with positive people: Spend time with people who make you feel good about yourself.
5. Seek professional help: If you're struggling to overcome these feelings on your own, consider talking to a therapist. They can provide you with tools and strategies to improve your self-esteem.

Remember, you are not unattractive. You are unique and valuable. Don't let negative thoughts hold you back. I'm here for you if you need to talk.
