I no expert by a mile in these kind of situation. People need to see the worst before they'll realize what they have missed out on. I'm a firm believer that you can grow to love someone, so maybe you admitted your feelings may have planted a seed on her heart. If I was in your position just be the bigger person and tell her that you'll be there for her no matter what (even if she doesn't share the same feelings as you). Also learn to respect yourself more you sound like an awesome person and hopefully you'll find that special someone who will see that very quality.
Do something special for your mom and reassure her that you wouldn't do something that stupid anymore.
