I'll be super honest about this. This is not going to be a short explanation, but more of an essay of my experience. I hope me sharing this doesn't bother anyone.

I'm pretty young and I don't think I know exactly what I'm feeling. This is made worse because for a long time I primarily had just accepted that I would not really be in a relationship with anyone for a long time. I've never been a very attractive person, and at about 13 I realized "I don't think anyone is going to be very interested in me, and I have other things I can be doing than pursuing relationships. Because of this, I don't think that I'll be in a relationship for quite some time, if ever."

Rather like you have accepted the fact that you cannot fly, I had accepted that I was not going to develop a relationship. I'd gone years without worrying about it. It was a fact of my life, a part of me, that didn't trouble me and didn't worry me. It was a problem I'd put off indefinitely and would deal with later.

This all changed quickly and recently. I had fancied a young lady for a while, but I'd never told her. Eventually I felt terrible with myself because I'd never had the guts to tell her how I felt, and I just wanted to get it off my chest. Let me tell you, the moment she said "I feel the same way about you" was one of the greatest moments of my life.

Now I feel a constant warmth, like a hug but perpetual. When I think about it I feel a buzz like a summer breeze in my mind. I don't know if this is love. But I know I never want it to end.

EDIT: I feel as though I could talk about this for quite some time. These are entirely new feelings for me, and I very much enjoy trying to quantify them.

It is peaceful, in that it brings a strong force of relaxation and content to my otherwise anxious, worrying thoughts. However, it is also a feeling of unsurety because I don't know what I'm doing. This is a part of myself I have never explored and I feel I must tread lightly, while at the same time wanting to abandon myself to these feelings.
