PCOS and weight loss

I have not mentioned it before but I have a condition called PCOS. Polycystic ovary syndrome (PCOS) it is very common, affecting 5–10% of women.
Polycystic ovaries are ovaries that contain many small cysts (about twice as many as in normal ovaries). These cysts are egg-containing follicles that have not developed properly due to hormone imbalances. Polycystic ovary syndrome is when a woman has other symptoms than just cysts on her ovaries.  

The symptoms I have are:

• irregular periods, or a complete lack of periods until the last two months when I have had two in a row
• unwanted facial or body hair …. sorry TMI, I should have shares in Gillette
• weight problems aka being overweight, rapid weight gain, difficulty losing weight -enough said
• depression and mood swings- ask Paul about this one lol

I find it very difficult to lose weight so every pound is an achievement to me. I have always had big legs and have not worn one pair of shorts in 25 years- so I am determined to loose enough weight to be confident enough to wear some on my holiday to Florida next year! I have lost 2 pounds this week which I am happy with as it is from walking 40mins a day as we are not going to the gym at the moment. I can’t decide if I should do weekly or monthly weigh-ins, the dilemma is that if I don’t lose anything or even put weight on week to week I could get despondent,which will mean I work less hard and will never loose any weight!
