Welcome to WHL! You've come to the right place to find people who understand what you are going through.
Some of your symptoms sound familiar to me. I also have problems with indigestion, and I take a prilosec daily. I wonder if that is part of what is causing your loss of appetite?
I can't do too much exercise, either. Just do what your body tells you it can stand. I mostly like long walks with the hubby.
Problems with the menstrual cycle, endometriosis, etc. seems to be common with autoimmune issues. I had some pretty strange issues with them when I was young, but did fine while I was having and nursing babies. I'm at that point in life when I'll be glad when they end for good!
As for telling people - I use a cane, so its obvious that I have some mobility problems. I have a mixed bag of autoimmune issues, so when people ask I just tell them that I have autoimmune issues - sort of like Lupus. Most people are pretty understanding and try to help - especially when I fall, which I tend to do. I used to teach high school kids, and I explained my issues to them the first day of class. They were very understanding, and were very protective of me in the crowded hallway. I fell in front of my classroom fairly often, but the kids would help me up and we would go on with the lesson.
I'm sure that some of our experts will come along to answer your questions much better than I did. Look around the site, read the stickys, and read threads that interest you. You will probably find a lot of answers to your questions.
I've lived in both Oklahoma and Texas. We were stationed in Ok City at Tinker AFB over 20 years ago, and we lived in San Antonio for 17 years - at Lackland AFB.
