Struggling with this weight loss thing...

I have been struggling as well. When I try to lose weight, it seems like the reasons that I overeat come into play and I'm forced to look at past pains in my life and ones that I'm currently struggling with as well and to avoid the pain, I just eat and try to forget about it. I know it sounds stupid, but I am going to really start reading the Purpose Driven Life as well and start to tell myself the reasons why I have to do this. I know I need to do it for my health...I really do, but it just seems like I give up on myself sometimes. My mom has been telling me for a long time that I need to start caring about myself and that she thought I was struggling a bit with my self-esteem. I don't really see that...I think I believe in myself...but then I hear things with the negativity around me where other people don't necessarily believe in my decisions and think I need to do other things than what I believe, so I just give up. I tell myself what I believe isn't important. Well, today, I'm going to start changing that and if I ruffle a few feathers, I'm going to tell myself that while I normally don't like to do that...that it really is ok for me to do sometimes.

Abba, please give me the will power to do this for me. I know I need to do this for me. Help me to believe in myself and know that You above all believe in me too.
