I thought some more about the situation with friends. It is true that I don't really have close friends now (we all went through some changes, normal for our age). Although I don't have many friends now, I felt "connected" to some of my friends in the past (only a few people, but I did). There were some "friends" who were abusing and manipulative, but they weren't close to me so it was not difficult. People who I connect with are not dysfunctional. Of course, we all have some struggles, but nothing what would have influenced our friendship.

Based on this, I don't think the problem is that I would attract dysfunctional people.
