Beyond overwhelm

I Joined in March, love Brooke and what she offers. I feel that i have all the issues she talks about: overeating, negative feelings,the after effects of my divorce, being a single mom to 3 kids, i can barely get them to listen, i move in with my mom,(very difficult), financial problem(the biggest of them all)I understand that i have to focus on one issue at a time so i chose Money because i need it really bad to give myself and my children a better life, However i would wake up really happy and determine to change my life for the better then something would pull me back 10 steps, it could be my mom saying something to me or something came up with my ex husband or i have anxiety from starting my own business. How do i continue to focus despite it all?
