Hello and welcome to Psych Central, delusions23! I think many people want a really good friend they have things in common with. I think of the character Anne Shirley from Anne of Green Gables who wanted a "bosom buddy." But I don't think it's possible to find an exact twin. I actually have an identical twin, but she is not exactly like me!

I agree with the others. Talk to a therapist to see why you are so obsessed and to help you with your interactions with other people, so you won't be so miserable in your searching. Again, welcome!
