How do I convince myself?

That was beautifully poetic. If I understand right, you love a girl that isn't unattainable currently. Could you give me a bit more information? I understand not being able to be with the person you love and want to be with, on many levels. With some more straight forward information, I think I could help you at least some.

I know how you feel and honestly It's really really really hard to let go of someone you think that passionately about so there is no real way of getting over her, just fool around with someone else (not particularly sexually) but like kissing and hugging... friends with benefits to distract you and who knows, you may fall in love with someone else. I mean you could even write some sort of 'goodbye, moving on' letter but you dont send it... write all your feeling down for her and whatever then put something like 'But it's time I moved on.... Goodbye' Just to put your mind at ease a little.Good luck with moving on, I know how difficult it is.

I've been there - I had someone I felt that way about someone for a very long time. I don't know if this will be helpful to you but what happened for me is that I never really "got over him" or "moved on" not on purpose at least. I just got to the point where I had to go on with my life. It was hard. I missed him all the time. I grieved. I was angry at the universe. But eventually it.... it didn't go away but it did fade a little around the edges. And soften into a sort of melancholy.The thing that helped me most of to find things to do with my time. Find work. Make art. Meet people. I still haven't had any other serious romantic relationships but I do have friends now and other connections and life is... not good exactly. But I get by.
