Hi. You know what? This doesn't really sound like co-dependent to me, because these people that you are attached to sound like positive role models for you, who maintain appropriate boundaries. It just sounds like you have wishes about them filling some needs that you have to be taken care of. Those are legitimate needs. It could be a problem if you can't accept their limit-setting, or if they aren't able to maintain clear limits with you. You are nearly an adult, but you still have a great need for nurturing. That just tells me that some nurturing has been missing from your life, and you still have unmet needs. If therapy is an option for you, that would be an appropriate place for you to get some of those needs met, learn about boundaries, and become more able to focus on equal relationships with peers where you are an equal partner and don't need to be dependent. Especially since this need for nurturing seems to be torturing you, I hope that you can get some help with sorting it out.

How is your relationship with your parents?
