The simplest answer can be the hardest to accept. And you already have it! Be yourself; live your life. That's it. There really isn't much more than that. You don't have to do anything other than that. In time, small numbers of women will mentally get to where you are. Without you even being aware, you may be a living example of another path to a girl, or another woman. Just by being you.

You say you feel like an exception. In this regard, right? Wonderful!! Feel that. Hopefully, you'll come to peace with that feeling. Or at least coexist with it. That's one path to "wise crone"hood, so to speak. Your experiences and knowledge will be needed. Find other connections with people. They don't have to be like you to be friends, do they? (okay, maybe remember to be joyous and grateful, when you're ready. You have your path, and may choose to sidestep drama and trouble in the form of males. Not every woman is capable of that. Good on you!! I'll celebrate for you now, before you can for yourself. Signed, another woman who has been, and continues, on that "I am enough/all I need" path. Edit tried to clarify
