Weight loss, motivation, fitness - Newport, South Wales

Hi Everyone,
I am looking to meet people who are seriously into getting into shape!
I've lost 15kg so far but find it very difficult to loose a bit more.
Like today, for example, I ate almost all Cadbury Fresh Cream cake and don't even feel guilty for it.
I was supposed to go to the gym but don't even feel like it now... I was there yesterday and will be there again tomorrow but feels like I don't really want to go there... Once I'm there I feel great for all the calories I burn and my mood is much better.
Sometimes I also feel like my boyfriend is not motivating me enough to do it...
I love playing tennis and could definitely do it everyday as long as I've got someone to play with. Going to the gym alone is quite boooring... I go to Fitness4Less in Newport - maybe there is someone who goes there too? It so much more fun when having someone by your side.
I can do swimming as well. I am quite flexible... Working 8am - 4pm Mon-Fri.
I really really hope to find someone here.
Now time to eat more cake... :)
