G --5---7------7----------------------5---5-----------
D -------------------------------7----------------------

And then struggling from here. Please help

 

Song looks like it is in C major and Dm might be one chord. Play the individual notes in the chords of C, Am, F, G and figure out the notes by ear instead of going by tab. Add other chords as needed (Dm, Em etc. to see if they fit in).
