You can heal this
It is possible to heal your condition without spending a lot of money. The smell that is coming out of your body is a result the rot and decay that is going on in your body. For most people, this is a result of diet, eating foods that don't digest cleanly in the body. The Standard American Diet will ultimately lead to bad health, and the symptoms you are experiencing are a result of such a diet.
A very clean diet, such as a low fat raw vegan diet, will heal your condition, given enough time. However, many cannot bear to live on a diet of only fresh fruits, vegetables, nuts and seeds in their raw and fresh state. But if you want to experiment, or use such a diet as a cleanse to see if you have any improvements, by all means, try it. By low fat I mean 10% or less of the calories come from fat.
If you can not do a low fat raw vegan diet, then try a low fat cooked vegan diet, with lots of raw foods included. If this is still too hard, then try a low fat vegetarian diet. Ideally the foods are whole foods, minimally processed (or not at all), in their freshest possible state, and organically grown.
The foods that ought to be eliminated from your current diet, in order of benefit in removing these foods are:
other animal products
In addition to cleaning up the diet, you want want to also practice the habits that create health: getting plenty of rest and sleep, exercise, fresh air, sunshine, clean water, reducing stress and anxiety.
