Stopping meetings is much more serious than stopping service. Your friends won't shun you so fast if you just quit service. Maybe try that? I quit within a month or two of waking up. Couldn't handle it. Wife was upset at first, but she barely goes out now too.
Seems like she is trying to make up for your lack of performance? Does she know how serious you are? Perhaps try the angle that you can't lie, you need to be hones. Your conscience is killing you, and must be honest.
