You're definitely in the right place here. Changing your habits/life is definitely the right way to go about it. It's no good fixating on only eating better if you go straight back to your old way of life once the weight starts to come off. It's all about changing your habits for life - and it's hard!
Welcome and good luck with your weight loss. The amount you need to lose is very achievable, though I know it feels daunting when you start out. This is a great forum for motivation and support, so you're in the right place! xx
