Going to Disneyland in 41 days!! I need some help

I'm struggling with stay in my calories and to stop over indulging. I've been doing this for 220 days and lost 4st 2lb I would like to lose another 8lb and I would be really happy. Ive also increasing my exercise because later this year thinking about doing a half marathon for charity. But right now I really just need support and someone to talk to. So I can keep on track and at the sometime I could help others to reach their goals.
