I wouldn't call it weird, but as someone else who has had that issue throughout my life, I would say that it is very good you recognize that in yourself now. I would try to figure out WHY you are attracted to these people. Is it because helping people makes you feel good? Do you feel like you don't fit in with 'normal' people? Are these people using you for your ear/help/money/time? Are you repeating patterns you learned as a kid, trying to recreate a bad relationship with a parent so it goes right this time?

I've found that as time goes by, I am more and more frustrated with this tendency in myself. I wish I had learned earlier on how to associate with 'normal' people - not that anyone is really normal, I get that.
