For GAL suggestions, let me mention some of what I did when we lived in the interior of Alaska, even in the winter. I had 3 kids then, including a baby (so you know I don't want to hear about how you are 'too busy' to GAL).
Inertia is the greatest enemy to GAL. Overcome that & you'll be well on your way to a happier, more fulfilling life.
IMO, the more you overcome inertia, & focus on your own work, the better your R's will be with all people, including your w.
I volunteered at a battered women's shelter.
I coached a girl's softball team, two summers (my older D was on it).
I was on the board of directors for Wrestling, (b/c our son wrestled).
I auditioned for community theater and met some fun creative people. I got cast, too.
I did stand up comedy (and yes, I still do it). I did a whole set once on a MLCs at the Improv. It went very well.
I learned to cross country ski, became a better shooter.
I Learned to hunt big game, to deep sea fish, & I got better at downhill skiing.
I learned to use a snowmobile ("snow machine" to Alaskans) I loved riding it.
Learned to fly a plane, & got a pilot's license.
Went skydiving. Loved it so much I did it again. And plan on doing it again, soon!
Edited a book. (The book ended up on the Best Seller's List. Who knew?)
I Worked out 3-4 times a week, and I really did get in excellent shape.
Looking good made a world of difference to me. I then found a work out partner and began socializing after the work outs.
Saw a therapist and for some months, went on ADs.
Took a pottery class (very odd for me to do, but I liked it a lot).
Joined the Officer's Wives club after 15 years of active duty.
(Wish I had joined sooner! Met two women who are life long friends to this day.)
Joined a writer's group
Took a class in Conversational French --(( Maybe YOU can tutor or teach German, AND OR take another English class? ))
Took a class in Italian cooking
There is more, but I just wanted to suggest to you a few things you can do that do not cost a lot.
Other than skydiving & pilot training, most of these ^^ activities were free, or quite cheap.
Later, I went on a serious trip with my children, and it proved how much fun and how many adventures we could have, with or without their dad.
Hope this helps.
