Get a new Doctor!!!
You sound like me! I have suffered from health anxiety (still do really) in the same way you did. Had raised liver enzymes, thought i had hepatitis wouldnt go back to retest. Left it for years, even turned down a good job because i was scared of having to do a medical. Had DD2 and eight weeks after was in agony - Gallstones. Not life threatening, but fucking painful. IF i had gone back and taken further tests i could have them removed before it ruined what was supposed to be a lovely time with my newborn.
NOW im not suggesting for one tiny minute that you have gallstones, and even if you did, so what, some people have them and dont even know. Its not a big deal. I think that the amount of alcohol you were drinking would have definately given rise to the elevated liver enzymes. This will happen when the liver is under pressure, it doesn't neccesarily mean there is ANY damage at all. The fact that your enzyme levels have gone down is a really really good sign. There is not just one liver enzyme that they test for, there are about three i think and the ratio of these in the blood can give a suggestion of certain conditions over another so, if the doctor was worried re hepatitis he would have suggested a blood test. So many things can cause this, having taken paracetemol for a while before you are tested. A high fat diet. STRESS!
Has your doctor not suggested some sort of counselling and possibly medical treatment for your anxiety? Im really surprised he/she hasn't. I let mine go on so long and it drew to a head when i completely lost the plot, went to the minor injury unit in absolute hysterics. WHy? I thought my tonsils were tumours!! Reasonable mistake maybe? Maybe, but i have a biochemistry degree and Phd in developmental biology - i should have known better!!
I convinced myself i was HIV positive and passed it on to DD1 - I really withdrew from her because of this and has impacted on our relationship terribly.
Now every lump bump cough splutter sends me into abject panic, but i am on medication now and its getting under control. I suffer with depression as a result of my anxiety and if you are not careful you will end up the same so please go back to your doctor and ask for a referral for counselling and consider some medication in the meantime.
Not sure i go with the highly sensitived nerves and adrenaline theory, im not a doctor but i am very interested in this area and ive never read anything along those lines. Anxiety is often a result of inbalances in seratonin which is a feel good hormone released in the brain. Most medications that treat anxiety work by trying to restore the balance of seratonin in the brain.
You really do sound like me, constantly looking for reassurance that all is well. Imagining your children without you - ive played my funeral over and over in my head, imagined my DD at school without me. Its terrible and there has been nothing wrong with me. Apart from my anxiety which is just as much of an illness as all the nasties you imagine might be wrong. It needs treatment, for some that means medication for others, counselling is all thats needed.
Please ask for help with this, you dont deserve, or need to feel this way.
