45 yr old Mom of 5 - need motivation and support!!

Hello everyone, I am 45 (soon to be 46), a Mom of 5 daughters (25, 22, 10, 9 & 6). I have been overweight most of my adult life starting right after my first pregnancy. 4 babies later and I am now at my heaviest weight ... 260 . I want to be healthier for me, for my family, for my husband! I want to be a better role model for my children and be around long enough to watch my children grow!
I am looking for motivation, support and family friendly recipes as it is SO hard to make separate meals for myself.
