Hi Lynda,Welcome to HealingWell! Wow, you are going through some tough times. (((HUGS)))First and foremost I think it is important for you to have some relaxing alone time. It is easier said than done, I know, but still imoportant. Do you meditate or practice any sort of relaxing techniques?
Since you don't have insurance I suggest trying OTC meds like probiotics and Digestive Advantage. You can also try taking a Calcium supplement which will help with the D and soothe any inflammation.
Next, you should probably try keeping a food diary. Document what you eat, how much you ate, at what time you ate, how you were feeling when you ate it, and then how you felt afterwards. You could end up finding that you are lactose intolerant or that you have a wheat intolerance or that you have a food alergy. Even if you have none of those, it will still help you pinpoint exactly what foods are bothering you.
Does your area offer any kind of public assistance? You may want to seek some help and possibly get in to see a GI specialist.
I'm sure others will be around shortly to give some input.
