ABC's of Love (updated)

Alone is what I felt for the longest time
But then I found you and everything became fine
Cause you showed me what love was all about
Definitely something I did at first doubt
Everything that I have been wanting to feel
Finally was in front of me and it was real
Giving you my heart did take some time
Happy thoughts though now fill my mind
In time I hope that you will see
Just how much you mean to me
Knowing that I have you by my side
Lets this road of life be an easier ride
Many things have changed for the good
Now I feel how I never thought I could
Others too see a change in me
Please can our love always be?
Quiet nights together, just lying in your arms
Really make me feel safe, away from all harm
Sweet dreams I have every night
Trusting that you'll always treat me right
Unable to live without you for a day
Vow to me that you'll always stay
Walk with me hand in hand

What do you think?
This is as far as I am getting I think because I am completely stuck on x and z. Any suggestions for those letters??
