I don't want new friends
Are you saying that because you have enough friends already?
Not really, I have a few but I don't interact with them
If you don't interact with the friends you have now, doesn't that make you lonely? If you're lonely, you should look for some new friends to make if you're unhappy with your current ones. It's not good for you to just spend all this time by yourself!
That sounds like way too much work for me. I don't want to do it.
There are plenty of low effort ways to make new friends if you are lonely. Have you tried joining an online community?
