Since I know a lot of people are really bored staying home and just want to go outside for a walk on a sunny day and just enjoy that day, but the situation is clear and please stay home and stay safe. I'm gonna enumerate some things you can do while being at home.
I know some people are really lazy and just want to lay in bed, but if you are bored this is the right time to clean something like a wardrobe, kitchen, room....
If you are a girl experiment with nail polishes and give yourself a manicure or pedicure, it will be fun .
You can also read a book it is really good for your brain and it' s relaxing.
You can start a new series on TV and binge watching it.
Play some games like monopoly, cards, etc...
You can also workout a little bit, it also helps to boost immunity, it doesn't have to be a hard workout, just do a few exercises.
You can also start a blog or even a vlog, it can be for fun, just for you  .
Bake some cakes, muffins, brownies, something fun!
Learn a new language you wanted to learn for a while, go for it!  I hope I gave you some ideas how to kill boredness in this time and I would also wanted to know what are you doing during self- isolation and do you have more ideas!!
