Ina, one of the things that I do to keep myself busy, is to study online. Like you, I married as a teenager (18) and spent most of my life raising my kids and taking care of the family, and working odd jobs for extra money as I could.
Since I am basically an "outside person", my hobbies were horseback riding, and camping and fishing with the kids.
Now that I am physically not fit to do those kinds of things (for the most part); I have learned to keep myself busy on the internet when I am not able to get outside.
I have a huge interest in the history of the world, such as archeology, as well as when the dinosours actually lived, and do they still exist (just called by other names), and things like that.
So, whatever catches my fancy, I read, study, and watch videos about it. sometimes I post about things in the forums (and mostly make people wish I would not, I suspect.....but, oh, well.)
There are some really great tutorials for drawing on the iPad, and the new iPad Pro that just came out is especially designed for people who want to draw on it.
I would love one of those, and I know that you would love it, too !
Watch the video about it from the Apple presentation (search on youtube) that shows all of the amazing things that it can do, and you will want one for sure !
It is just a little larger than the one you have now, so easier to do artwork with.
Here is just a little video that shows someone playing around with the iPad Pro and an Apple Pencil, which is designed to use with it.
