On the transition from Asus to Am, just hammer on the first fret on the B string. 
And on Dsus, you can hammer on the sixth fret on the B string to make it Dm 
throughout the song. This is my first time submitting something, I hope you like it :)

     I feel it everyday it's all the same
          Dsus4		             F
It brings me down but I'm the one to blame
           Dsus4              Bbsus
I've tried everything to get away
          Dsus4
So here I go again
            F
Chasing you down again
       C  E
Why do I? do this?

Asus4     Am    Asus4     Am
Over and over, over and over

F#5			      Em
So many thoughts that I can't get out of my head
F#5			   Dsus4              Em
I try to live without you, every time I do I feel dead
F#5
I know what's best for me
Dsus4
But I want you instead
F#5			    Em
I'll keep on wasting all my time

Asus4     Am    Asus4     Am
