looking for support!!

I am 33 yrs old and i have 120 lbs to loose. I have not much support at home. My fiancee is always working and he has really bad eatting habbits. All of my friends are tiny they dont know how it feels to be a big girl and i would feel weird asking them to walk wit me. Or help me stay on track. So I was hoping that I could find a group that did challanges and held everyone accountable. Or was just there when u needed to fight them cravings or needed alittle pushing to get moving. IF there is such a thing on here Please message me I would love to join. Ill keep looking on the message boards.
