What I would do personally is break of contact temporarily, and work on myself for awhile. That's what you need, to work on whats there and now.

In order to work on the bigger stuff you have to start out small......don't jump ahead of yourself, especially for something your not even sure of.

Confrontation is essential to healing, in my opinion. What if they have no idea how you feel, or how strongly they effect your life? It's important they know the complete truth....even if it hurts...but that comes later.

I hope you get this all worked out. Good luck with that.
