I have it as well. With some lifestyle changes which really are benefical to all you will lead a full and happy life. You need to make exercise a daily routine and watch what you eat, which is what everyone should do. Follow a dr or diabetes teachers diet, you will lose weight and also feel better then you have in a long time.
Best of luck to you. It is not as hard as it seems. Don't keep junk food in the house, that is number one.
Make events about the fun not the food. Eat to live, don't live to eat.
If you take a moment and watch what the average American stuffs in their mouth you will be surprised. Heavy people are so for a reason. Look at what they eat. They don't even realize how much they eat or how many calories they consume in one meal. Often one meal is all the calories they should have in one day. If a person is 100 lbs overweight they are probably eating three times as much as they should in a day in calories that is.
Once you get the diabetes under control you will feel great and be much happier.
A support group is great advice. It will be ok. Life goes on and you will find eating differently to be fun and healthy. I wish you all the best.
