Hi spin, I've read the entire thread and hope you're feeling calmer now that the results of those scans have come back all clear.
I'd push for an ultrasound of your gallbladder. It's a non invasive scan and will tell you if you have gallstones.
Your symptoms sound exactly like mine, only I went down to 6 and a half stone before my diagnosis. Couldn't eat a thing without throwing up and having diarrhoea - survived in dry biscuits and sugary drinks at the end - felt excruciating colic if I moved or carried anything, or even wore a tight bra. Even breathing was difficult.
The pain in the upper and lower left side, reaching round to the back like someone stabbing me, the feeling of acid, the yellow stools all point to a gall stone being stuck in your bile duct.
I'd insist on having an ultrasound and taking it from there.
I understand you are the sole parent and that must be hard for you with your dcs especially when one has a disability, but I think you are making things a lot harder for yourself psychologically by turning this into a major catastrophe...... You absolutely must stay positive, and stop talking worst case scenarios with your dcs. Even with NT kids, it's TMI for them. Talk with a friend if you need to download your fears. There just fears, not the truth, and the kids don't need to know.
Sometimes we need to accecpt that we need help in our lives, and this may well be a wake up call to you to enlist some people to help you with your life and kids.
No man is an island, and my feeling is that you've done yourself no favours by "being strong" and not getting help before this and being "invincible, reliable" mummy who never goes to the GP.
You're human and your mortal, so get help and start to widen your circle! It will teach your dcs more than you can know to see you asking for help from those around you.
Please keep things in perspective, and get an ultrasound for gallstones. Remind your GP you are jaundiced, and insist on an ultrasound.
Please stop over sharing with your dcs and talk about your fears with another adult and with us.
I think it's important that you are very careful not to lay your fears on them, it's not fair, they can't do anything to allay your fears, and their stress levels must be sky high. If you have to tell them any medical details, please wait till you get an diagnosis.
Sorry to lecture, but I had a mother who was a hypochondriac and she used to wind us up to 90 when we were only kids, by telling us her FEARS about what was wrong with her, so perhaps I'm over sensitive to the catastrophic outlook..
You need to get support from people in real life.
You know, you may think it's good to be self reliant, (and it is to a certain extent) but I would argue that it's not a good role model for your kids to always "push through" on your own- you're not invincible, no one is, and you don't live in the great Wild West Wilderness, with no neighbours or people around you. Be gentle on yourself and get help. You need to develop trust I think that people will help you. They will you know, just look at this thread!
I do feel you may have gallstones and an ultrasound will diagnose that simply and quickly, with a simple laproscopic op to whip it out and put a stent in your bile duct.
I'm sorry if I come across as being a bit stern about the over sharing with your dcs.
Good luck with it all.
The very best of health to you, and happiness for your family.
