14 days is fantastic.
Think of it this way? If you feel this anxious after 2-3 years heavy drinking can you imagine how it will feel if you go back to drinking and then try to quit after 17 years of hard boozing (like me?)
You know you don't even want to go through that! So just hang in there my friend. You feel alone but we are all in this together and supporting each other!
PS - Your symptoms are your body, nervous system and mind getting better. It feels c**p but embrace it. You're getting well!
