keep a food journal

I need to stop being so self critical of myself.The few times I’ve began my food Journal,The second I messed up,I’d quit.I just become so frustrated with myself and the way I look and become very discouraged,but I need to keep with it even through the mess up days and find out what triggers me to do so,but that’s very distressing and I feel that I don’t have control over myself.Hopefully tomorrow will be a better day.
