Need some girly guidance!!!

Jessica
I feel like absolute rubbish at the moment! I feel like a terrible mother, terrible wife (not married but might as well be!) and just a really bad person :( I have real issues with insecurity at the moment, and really struggling to get rid of this horrid feeling! OH says I'm being silly thinking he deserves better but I just can't shake the feeling he wants me to make more of an effort, any girlies (or guys! Always up for a males perspective on things) got any tips for making yourself look just that little big more attractive? And getting abit of motivation to work a little harder?
