Sorry, it is the phone. So you are saying:

I am a young woman who is not at all bad looking, who is sociable and does get attracted to people and likes being in good company, but much more so she likes thinking of herself as superior to others and ready for self-sacrifices other people would not even consider.

Which is totally fine as a phase of the years of your youth. As a poster above noted, just do not commit to this.

Back to "accept". The OP talks about a decision you made. So you already made the decision, but now are in need of help accepting your own decision? Not terribly logical.

You have had attractions, but have never been in love,
I think, and two things make me think that.

1. You write about being in love very casually, in the same sentence in which you write about liking to spend time with people. Plus, there is no emotion in how you describe it. So those were probably fleeting attractions
, which is perfectly fine, but not love.

Second, when you truly love someone but forego pursuing that love for some reason, it is very hard. I have done it, and lots of people I know have done it, for reasons that have nothing to do with yours, and it is hard, and people talk about such sacrifices with emotion even 50 years later. You write in a completely unemotionsl and totally cerebral fashion, and in that cerebral fashion you created a fairly logical, except for the "accept" part, internal dogma - "I had no positive role models so I will never be caring and loving so my gift to humankind is my total removal of myself from the world of relationships, amen".

All of this is good news, because it means that you are theorizing. When you fall hard for somebody, the sand castles of your theorizing will get smashed, and you will find internal motivation to care for that person despite your past. In the meantime, since you cannot identify love, you can read about it - Goethe would be a good start.

Note that there is an element of self-adoration in your post, almost as if you reveled in being different and making unusual choices. All of that is, of course, completely within the range of normal adolescent development and not a cause for concern. You have a lively internal life and I wish you all the best in the long run.
