Best thing to do here would be to stick to the No Contact thing. I know its hard and i know im not the best placed to give such advice as im not sticking to it myself but if she has made it clear, no amount of things you say will change her mind - only she can do that. If you still want to get her back, remember what it was about you that first attracted her too you. Focus on improving this and magnifying it not for her but for yourself. You will get over this soon, or attract her back whichever is supposed to happen, will happen.
