Hi Lizzie!
Welcome to SR!
I hope that you will stick around. Keep reading, keep posting. There are many wonderful people here who can share their Experience, Strength, and Hope (ES&H) with you.
I understand your concerns about attending an Al-Anon meeting in a small town, but as others here have said, everyone in the meeting is in the same position and completely understands what you are experiencing. The wonderful thing about Al-Anon is that we learn we can be happy regardless of whether or not the A is drinking!
Hugs and prayers, HG
