Hi bfree,
Cut that person out of your life. Not a friend, I think as others have said, more like the enemy. Some people are so sick...
Day 5 is great! You can do this! I thought I was hopeless after years of boozing and I got sober! You can do it if I can.
Don't isolate, but consider going to an AA meeting. Just being around other understanding people can make all the difference.
Hang in there.
Jup.
