I feel similar to yourself op. For as long as I can remember I have wished to look like someone else, any body else. I feel disheartened when I see my reflection in the mirror, sometimes I feel so ugly I want to scream, take my glasses off and break them, although I know its not just about wearing glasses! But I don't let this get in the way of everyday life, I can't, I have kids, so I just get on with it.
I remember feeling like this when I was quite young, about 11, 12, wondering why I looked 'different' to my friends. They were all blossoming, while I felt like an ugly troll. I was bullied because of my face - its really quite round.
I'm sorry you feel this way about yourself. I don't know what the answer is, but it can never be so bad that you wish to end your life, you must recognise this. I know (I don't have many friends) different women, some are absolutely gorgeous, perfect make up and are very photogenic. And I know other women, who are gorgeous too, no-make up and take wonderful photos. Their beauty is their smiles. It comes from within, once you are happy inside, it shows on the outside.
