Yes, when my HA was at its worst I had a whole heap of digestive issues.
I did become physically unwell, but it wasn't anything that was physically serious, it was brought on by being very mentally unwell and focusing on my health and some was psychosomatic.
When I had my heart attack phobia my left arm was in constant pain. I couldn't believe my GP when he told me it was psychosomatic. That and a mixture of being so tense I was holding my left arm in funny ways.
I am still amazed how my physical symptoms changed with each worry and then stopped with MH treatment. Your symptoms are things I have had when my HA was at its worst.
Being in such a high state of anxiety will play havoc with your physical health. It is amazing what your body can do when you have HA.
When I got myself in a state over my smear tests results I started to bleed. My husband told me that it was because I was going to the bathroom all the time to check for bleeding. The constant wiping and prodding about caused a small bleed due to irritation, that I blew up into a big thing. I didn't believe him at the time.
I know that the second my anxiety gets bad my digestive system will play up and I will have a whole manner of symptoms, which really are simply caused by stress and fear.
I spent quite a while, along with many others, trying to talk to you and help you. I can see that you aren't in the right place to focus on any of those messages. I have BTDT so I am not judging you, but I hope in time you can come back to this thread and focus on them, read them properly and act on them.
There is light at the end of this dark tunnel. But only you have the power to start your recovery and find those better times. It seems impossible I know, but it isn't. I really do hope you can get to that place soon.
