I've tried everything to lose weight, and I've given up. Any ideas?
That's excellent! Congratulations! I hope you really have given up deprivation diets and phony weight loss schemes and products.
I hope you are now able to admit you cannot do it by yourself, and that you need help. There is help waiting from those of us who care, from friends in the same situation as you, and from your Maker. All you need to do is give up.
Give up the bingeing and starving. Give up the shame and frustration. Give up the self-abuse. Give up the "treating yourself" with harmful foods and snacks. Give up the attitude of impossibility. Give up the over-pleasuring yourself that is actually causing you pain and discomfort. Give up the burden of excess poundage. Give up the sicknesses. Give up the idea that you know what it takes to lose weight once and for all.
Now give up and finally let God help you with your life. Say a prayer for help right now.
