Amazing discovery, and I can totally understand how/why you would feel as you do (positives, anxiety, upset). I am so glad for you that this half sister was friendly and open with you. If she wasn't, that would certainly be more disconcerting and upsetting. I truly hope that relationship develops into something good. I'm glad your father finally fessed up about it. I could imagine you having some anger, so if you do, don't feel bad about that. It certainly seems like something you'd want to process with a therapist, though. Hugs to you, busymomof5!
