Break-up

Please give me advice.. I'm only 15 and just went through my first heart break. I love him so much and we were in a LDR relationship and he asked for a pic of me this morning and when I sent one, he never texted back and i haven't heard from him since. I mean.. I know I'm not the best looking, nor do I have the best body, but I really did love him.. Heck! I still do. It hurts so much though.. He was there for me through everything and now.. He's gone. I've never felt more self-ashamed in my entire life.
