Hello, Hopeful . . . let me give you my time line because my anxiety probably came first.
By the way, I do have a perforated right ear drum but the only thing that it prevents me from doing is high altitudes (like 10,000 feet) or flying (which I would not do anyway - anxiety).
At 16 I was diagnosed with situational anxiety and hypoglycemia. I had always been told the hypoglycemia could turn to diabetes, but with good eating habits, I have assured myself that this will never happen.
At 25 I was diagnosed with asthma. I worked hard through exercises and breathing to get off of the regular medication on my own and it is now considered low grade. I have a rescue inhaler I use a couple of times a year if I get around allergens. I get worried when I get bronchitis that I could suffocate, but I have had pneumonia from an apartment fire smoke and with medical treatment, I made it through that okay.
In later years, I developed IBS (knew this was benign, so never worry about that), osteoarthritis and sciatica. For a long time I was worried that my fatigue on pushing myself hard physically like when doing house work meant I had something else seriously wrong. I am 51 and have been assured by doctors that it is just part of aging and part of the pain. My husband suffers chronic pain as well and has lasted for years with it.
I would imagine your fibromyalgia is a lot like my husband's chronic pain. His is constant and seems to be everywhere in his body. He is on Fentanyl patches for his which only knocks it down. He has absolutely zero anxiety which I find amazing.
If you have assurance from your doctors that none of your conditions are life threatening and you look at how long you have already suffered from these, you can take some comfort in knowing that even though you are physically miserable, you will be, for the most part, okay.
When something starts hurting you spontaneously, think about what you have that is benign and recognize that your anxiety may be aggravating that symptom. I have to do that often with pains I have. Eventually they fade. If they do not or something new crops up, then it is time to give the doctor a call.
Take care and I will be here for you.
