Weight loss before I'm 30!

Hello I am Louise and I am29' I am 30 in September I have set this as a time to see how much weight I can lose, September is also when my little boy starts school!

My reasons for losing weight.. I just hate myself the way I am.. It makes all aspects of my life, harder and sadder.
I don't want to be the fat mum and Ben to be embasased. I want to wear nice clothes and look nice.
I have roughly 5-6 stone to lose but I need to do it slowly.. And get into my head that its a lifestyle change!

Anyway I am looking for friends to give me motivation and help
Thanks for listening!
