enlarged red blood cells and high blood pressure

i have beedn diagnosed with enlarged red blood cells and high blood pressure, i had a bad start to the year with my friend dying from end stage liver failure, but i was also a drinker, in july i was rushed into hospital with supra ventricular tachycardia, my pulse rate was 248 per min. as a result my dr is treating me for these blood cells and blood pressure, i havent had a drink for two months will it go away, or am i on the way to liver damage, please help, i am worried, if i had continued drinking would it have led to end stage liver failure. x
