As a lyric writer and Lead Vocalist myself, I won't go onto the rhetoric about 'You must have music to write music to'. In my opinion while it may be easier to add lyrics to an existing accompaniment, I myself perfer to do the same as you, and that would be a technique known as "Free Writing".

As far as songs not being relation to you, I myself usually write most of my songs that are not about me. If I wrote songs about me, usually they'd be just dull and ramble on, and on, and put everyone to sleep. Also, dont let thinking interfere too much with writing. For me, I usually close my eyes and relax for a bit of time to mentally prepare. Then I pick a topic that's on my mind at the moment. I'll then come up with a bit of a tune in my head, and then I dont think, I just let the lyrics flow out of my hand, into the pen, and onto the paper. Usually if i try to think whilest writing a song trying to make it specifically about something, usually it doesnt turn out right.

Also, empithy helps much.

Good luck,
