Who should I contact to get a better education about this and what do you advice me to do. I am learning guitar, but I am unable to get the music in my head out and play it on the guitar. Any help how I should progress and which road I should take?

That's really good
I think you could definitely look into pursuing this in your spare time if you'd like.

However, I really don't know anything about breaking into the business.. I just really wanted to tell you that you should take the lyrics off immediately.. since you probably don't have copy rights to that song, someone else could come along, snatch those lyrics, and make millions off them.. and needless to say that would just suck lol.

Thank you very much for caring to warn me. I knew something like that might happen but I got so sick of being a closet-poet LOL, at least now someone from somewhere in the world I don't know actually read my work who doesn't care to say its good to spare my feelings and said it was.
I guess I should keep searching for a way... I love music and lyrics... I wish someday someone will hear a beautiful song playing and it'll be mine... I can't imagine anything more satisfying

If that's truly what you want to do.. I say go for it.. I hope someone can help you figure out how to break into the business. I think as long as you have a really strong passion for what you do.. and you don't give up.. you can do it.

I googled how to break into the music industry as a songwriter.. just to see what came up.. and here's a pretty good site I found

It even gives a list of some schools you can get into.. that seems like a good route to go on.
Good luck!
