This is gotten too far. What you need to do is stop crying. I mean you need love from other sources. Pray God everyday and also see your friends as often as possible. You need hang put with people, be close with your family, relatives and friends. best thing you can do is be busy and work on yourself. meditate. There are good meditation apps(Like "Mediation" and "Lets meditate !"). Also practice forgivness - forgive every day something. People who forgive tend to cope with dificult situations better. There are mediation for forgivness and also prayers for it. You are weak now but all you have to do is find things that makes you strong. If you can afford then go to counseling or therapist. maybe you have a good friend or someone with who you can talk about your problems. That would help a lot to feel better cause sharing pain is always easier than keeping everything to yourself.
meanwhile take good care of your body and looks. This will help you feel better too and increase your confidence.
