For most people it takes decades of very hard drinking to cause liver disease.
Not knowing you, how many years has it been since you were 16 and started drinking?
“About 10 to 20 percent of heavy drinkers usually develop cirrhosis after 10 or more years. Generally, drinking 80 grams of ethanol daily for 10 to 20 years is required to develop cirrhosis which corresponds to approximately one liter of wine, eight standard sized beers, or one half pint of hard liquor each day.”
If you had liver disease it should have shown up on the tests you took.
How high was your Bilirubin? Do you have symptoms of elevated Bilirubin like jaundice (yellow eyes and skin)?
The symptoms you have described are not really symptoms of cirrhosis.
I have had liver cirrhosis for over 10 years and have none of those symptoms.
From the Mayo Clinic
“High total bilirubin that is mostly unconjugated (indirect) may be caused by:
Anemia
Cirrhosis
A reaction to a blood transfusion
Gilbert syndrome -- a common, inherited condition in which there is a deficiency of an enzyme that helps to break down bilirubin.
Viral hepatitis
A reaction to drugs
Alcoholic liver disease
Gallstones
Strenuous exercise can increase your bilirubin levels.
Caffeine, penicillin, barbiturates, and nonsteroidal anti-inflammatory drugs (NSAIDs) called salicylates all lower your bilirubin levels.“
Not to say that excessive drinking is a good thing. Drinking too much has many consequences other than solely health related. There are also social consequences and mental health effects from drinking too much as well as potential health risks.
My suggestion is to believe your doctor and consider trying to reduce your alcohol consumption if you can and getting help to stop drinking if you can’t do it on your own.
Also if you are not currently under treatment for your anxiety and hypochondria you may consider getting counseling to help with these issues.
Best of luck to you.
