Is it bad that I don't have any friends but I pretend that I do?
It's not really bad, but why do you pretend to have them?
I don't want people to think that I'm strange because I don't have any friends.
It is hard making friends but your life would be better if you had people around you that care about you. It is difficult but you should try.
I don't really know how to meet people.
Try to join some clubs in your area because that can be a good way to meet new people. If you had a dog, you could meet people at the dog park. There are many community activities that you could get involved in that would help you meet new people.
