Hello, I'm new here but your title of no support system caught my eye. Then I read your post and can relate so much. The struggle of losing weight is very real for me also. A family member of mine sabotages me quiet often as well. She likes to bring me bags of candy knowing that I cannot resist. Of course I eat the candy and then feel super guilty. Then I decided that I have to try hard to be stronger willed. So my advise to you is to continue to try hard. Don't give up no matter what. Remember you are doing this for yourself and you deserve to lose the weight in order to feel better about yourself. Just picture yourself at the weight you want to be at and go for that goal. Buy yourself a nice out fit that you want to be able to fit into and hang it where you can see it on a daily basis as a reminder to you of where you want to be. I wish you the best of luck and just know that you are not alone in this fight. Take care.
