So sorry to hear that this is happening to you
@amalah and you deserve better. I can only speak from my own experience with my daughter who had suffered from panic attacks and anxiety for years and when she has these she also has major gastric issues. She has even been hospitalised on more than one occasion and had all the cameras, up and down, scans etc and nothing was found. She was also once accused by a consultant of being anorexic and was bringing all the gastric issues on herself! You can imagine how that made her feel.
It may be that your anxiety is also causing your other health issues and it is snowballing ..... you are anxious therefore you have gastric problems, which makes you more anxious .....you read your doctor thinks you could be a hypochondriac, which makes you more anxious, which causes more gastric problems. It's a vicious circle.
This is what my daughter put up with for years and we didn't know how to help her until she finally got some therapy and talked to a specialist about her anxiety and panic attacks. I can only suggest that you try this route, it may save you months of worrying.
My daughter still takes anti anxiety meds daily and has stronger ones to take if and when needed but she has it all under control now. I feared the worse when my husband, her father, passed away in July but even when we sat at his beside for 3 days watching him slowly leave us and were with him when he took his last breath, she was brilliant. I was amazed at how well she coped and she was a tower of strength for me.
Try not to be anxious, tell your doctor you are not happy with the 'hypochondriac' comment and that it is all very real to you, even mention what I have written above if you want and ask if you can be referred to somebody who you can talk to. Doctors are busy people and sometimes just push pills at you rather than getting to the root of the matter.
I wish you all the best and hope you will fully recover and 2023 will see you back to your old self again
