I've had friends tell me they felt this way too. My belief is that to each one of us our story and abusive experiences are the worst because they happened to us. It doesn't matter who's experiences are the "worst." If you've been abused and you're hurting because of it, those are valid feelings. You have a right to your feelings. The thing about life is that you can always find someone who has it worse off than you, or better. But the important thing is to honor your experiences and path.
