I am looking to join a kidney Support Group

I am looking to join a kidney support group that addresses questions of proactive lifestyle, diet and exercise.
I have a level 3b chronic Kidney Disease level.
I am looking for suggestions of a good diet.
My other related medical problems include dehydration related to a 40 year old ileostomy with my Colin taken out. Many episodes of dehydration, and type 2 diabetes with a 6.2 A1C. I have been taking pedialyte to help me contain more liquid and avoid dehydration episodes but I do worry if the high amount of salt and other electrolytes might hurt my kidney condition ? Any information or ideas how to deal with this situation will be much appreciated. Rick37
