Hi Six,
There are many people here on SR who have stopped in their 60s, and they are all very positive, and wonderful contributors. Lots of good advice above, and you will definitely be feeling better in a few more days.
Are you still working, or are you retired? If you are retired you may want to look into volunteering. Also, still lots of time to meet someone, and enjoy this stage of your life. You may even meet someone volunteering.
Keep checking in, you can do this, and I promise you sobriety is worth it!!
