an own song

I am making already a reservation, because, and this is a very hard one for me, I write a lot of songs. I don't know how to explain this, it stays in the head and it rests in the head. But, no joke, too shy to sing it, but this problem is going a lot better now.
I have almost no voice today, and it is a ballad, probably too sweet.
It started now, because this is my FIRST TIME in my 30 year old musical carreer, that I want to SHARE this song. I have absolutely nop idea how to write it down. A little fact, my guitar buddy was here last night, and his mouth was wide open, I even saw tears, by playing the famous Gloria Gaynor song, I will survive, using exactly the same chords, but I made it into a kind of sad ballad.
This morning, I started to play, first on a D-45 Martin, but 10 seconds later I started on my SJ-200, giving it the sound, really the sound I wanted, because of the crystal clear and lower sounding music. I started some where in D, using just the little E string, going from the second fret to the third fret, and playing the same pattern on the B string, also from the second fret up to the third, back on E string, where, using the E string second fret, I played, more "finger picking" the full D chord, singing a few words at the same time I was using 1 string from 2 to 3 and back to D. This chord was followed still using 1 string, the B, and again on the second fret taking A7, there are different ways, but I only used the D - B chord without my finger on the G string second fret, and going up with my fingers up tio the 5th and 7th fret, than back down. I did the same with the D chord, going up to the 5th fret, just changing my fingers 1 on the E 5th fret, one on the B 5th fret, and the other on the 6th fret on G string, up to 7th fret, using again the classic D chord and back down. IT IS NOT EASY TO WRITE THIS so don't kill me, I don't know how to draw it.
Playing this very sweet, soft and gentle, it was so beautiful, and I have to continue on this one, using other chords, matching, to finish this. You can try it out, or help me out with suggestions in my search for matching chords, knowing that the song starts from D to A.
Please can I have some advise, it is even for me now a little bit emotional, because it sounds so great. Lyrics will go about choices in life, where things got wrong, and why communication is so important. HOW CAN I WRITE THIS SONG TO SHOW YOU THE WAY OF PLAYING IT???
