Chery...I know how you feel. I felt like this right after getting out of rehab. I was scared to death of my new freedom and coming back home.
The way you're feeling is normal. Just stay focused, use the tools you have learned, and take it one minute, one hour, one day at a time.
As far as a beer on Sunday, watching football...I too never had a problem with alcohol. Actually, I could count on one hand how many times I've been drunk. But, with that said, every time I've had a beer, glass of wine, or mixed drink, it ALWAYS lead me to use or think of using.
