I read your other post and just had to respond, because I practically could have written it myself! This past fall, I became very ill. My list of symptoms was a mile long - multiple neurological symptoms, multiple GI issues, respiratory problems, musculo/skeletal problems, and mental issues. When the doctors couldn't figure out what was wrong after a few weeks of testing, I got on Dr. Google and came to the conclusion that I had scleroderma. (This is when my health anxiety started). I, too, have Raynaud's. I also have always tested low on pulmonary function tests (and have been diagnosed off and on with asthma because of it). At the time, I had all of the symptoms of scleroderma except the skin symptoms. I had my ANA tested, and it came back negative, which put my mind at ease about that particular disease. After a few more weeks of testing, it was determined that I was suffering from severe anxiety and a B12 deficiency. What I discovered during that time though, was that your constellation of symptoms (which were very similar to mine), could be attributed to MANY, MANY different diseases/conditions, most of which are very easily treated (like a B12 deficiency).
Anyway, I started taking B12 supplements, which helped tremendously, but I have still been having trouble with anxiety. Personally, I am not big on medication. I try to take as little medication as possible, and always prefer natural treatments. BUT...my anxiety got so bad, that two weeks ago, I broke down and filled a prescription for Lexapro. A mere two weeks later, I feel like a different person. My anxiety is SO much better, and my physical symptoms are about 80-90% gone. So, even though I was reluctant to try it, it has been absolutely worth it for me.
Finally, this forum has been very helpful for me. I read something on this forum not too long ago about reading medical forums. It said that when someone is diagnosed with a disease, every single ache and pain becomes attributed to that disease, even though there are many aches and pains that are totally normal and just part of being human. This was something that I had never thought of, but I believe it is absolutely true. So, just because one person with scleroderma said that they have neuropathy, it doesn't mean that the two are related. Ever since this fall, my anxiety tends to manifest neurologically, but I am no longer worried about having scleroderma.
You MUST stop googling!! I know it's hard, but the longer you go without googling the better your mental state will be.
