I know it's hard to not be scared Sleepie but I have really do have faith that you're fine
I hope your Dr will be able to sort out any concerns you have, and set your mind at ease.
I went through this too - I drank so hard for so long that I felt I deserved some bad health results and I became over responsive to every symptom my body presented...add to that immoderate use of Dr Google and I was convinced I was going to die.
8 years later I'm still here - and I feel safe in saying you will be too
