Hi Claddam,
Thanks for reaching out. I'm sorry that you've been feeling so helpless; health anxiety can take an enormous toll on the mind and the body. I'm glad that you've been able to trust and talk to your Doctor; hopefully he's helped to put your mind at ease knowing that all the results have come back fine.
Headaches, racing heart and not getting enough sleep are incredibly bothersome symptoms - but they do not indicate that anything serious is happening. Anxiety is also very real and very bothersome, but it is also not serious. Being able to educate yourself about all the different symptoms that anxiety produces (that mimics MS and heart failure) is so important. Some of the other symptoms of anxiety (which you may or may not know) can include increased heart rate, breathing rapidly (hyperventilation) or shortness of breath, sweating, trembling, feeling tired or weak, dizziness, choking, dry mouth, stomach or chest pain, diarrhoea, blushing, muscle tension and headaches, difficulty sleeping and nightmares. This is a huge list - but it can just show just how much physical symptoms the body shows when it's under emotional stress.
This also would explain your stomach churning and gurgling. I also know that it's normal for weight to fluctuate up to 2.2kg just during the day; just from basic human functions including digesting each meal, bowel movements, foods with sodium and water intake. It would also explain why you're feeling tired (or cutting out calcium may cause tiredness).
I hope that this info has helped put your mind at ease. This doesn't make you a hypochondriac or make what you're feeling any less real. It does mean though that instead we can work towards managing your anxiety so that you can manage the severity of your symptoms.
