Have fun, as much as is possible when under the weather. Trust your gut and your Higher Power that you'll make a good, healthy choice for yourself about going to the meeting or skipping this one.
There's really no wrong path.
And nothing needs to be decided right now.
I've gone to meetings with germs and found something I needed to hear, and understanding for others who do the same.
I've skipped meetings for other kinds of self care, like sleeping when ill, and if the God of my understanding has a message to get to me, other signs/readings/a phone call or something will help, too.
