You might have CSW syndrome
You could have other things but not HCV. Good luck with the drinking issue, maybe some culpability on your part for the bad decisions would help you deal with it all better?
"tonight my friends in UK where I visited after a year got me drunk"
You got yourself drunk, not your friends. You made the decision to drink so you own the consequences. A major factor in successfully overcoming any addiction is accountability.
BTW, your risk for contracting HCV is about non-existent.

You’re concern involves HCV? This virus isn’t efficiently transmitted via sexual intercourse, and you had protected sex; where is the issue? Good luck with your alcohol treatment program,
