I go on my own but here is the thing.... once you find a fellowship that you like, you will make friends and never be alone again!
Just keep going. Try different meetings at different times of the day. Go to Chip meetings, Big Book study meetings and speaker meetings and you will find different people at each meeting.
The great thing about AA is, whenever you are on vacation you can find a meeting in that location. I have met folks this way and been invited to join them for dinner after the meeting.
Our primary purpose unites us no matter where we are so don't be afraid to smile and extend your hand to introduce yourself.
