Is it really worth it to have friends?

Would you rather have lots of friends or none at all?
Are they really worth it?

Personally I would rather not have to interract with other people, only those that mean something to me, like my s/o and my parents. Other people are too much of a waste of time. I don’t want to have to think of them and to please them. I don’t need them, I am happy with my lot and the ones I have had have only been a waste of time anyway, and caused me grief.
