about to turn the big 30 want to get inshape

Hello I am looking for a few fellow female friends going on 30 to help motivate each other and give each other some challenges weekly maybe, while on this journey together whether we are trying to just get fit or to lose a lot of weight. having friends and others to help encourage is a way to start I believe in the right direction!! Also I am not really sure but I believe I am pre -diabetic I am unsure yet but diabetes does run in my family, and I have been dealing with a lot of numbness in my hands and feet, lately and well drs have done soo many tests they cant seem to figure out whats going on I think it could be ms or pre diabetes, so I figure maybe by changing some of the foods I eat maybe it would help, any suggestions to those who do have diabetes?
