My mind is making me fat!

I came to the conclusion that my mind is making me fat! It makes me feel like I can't get past my 260 mark!!! Every time I get close to it I set my self up for disaster. My mind says "You've been trying for so long to get past this mark, but it's not going to happen!" and then it says "Why are you even going to try?" I need to get my mind out of this thought pattern and get going or else I will be stuck here FOREVER!!! Spark people has helped me a lot, alone with writing in a journal. I write what I eat and what I am feeling. It can be anything sometimes I write the most random things:) I always try to stay positive when I write in it and find something that day that I did that was good, even if it was just something small. Last week when I got close to that 260 mark I set myself up and so I decided that I can't give up and I need to continue with my journal writing's! This week has been super hard because my husband is gone on a work trip and it's just me and the kids. I am finding it hard to get to the gym and I;m driving myself crazy in the house!!! We will see how tomorrows weigh in goes!
