Learning and Practising
A possible way to approach this is to think of the two elements of chords and fingerpicking, and focus on each one of them separately.
Chords: each bar contains 1 or more chord, play these on there own to get used to the progression. You can start with strumming each one on the beat.
Finger-picking: There are 3 distinct picking patterns.
Bar 1 to 4: this is a typical classical finger-picking pattern moving up and back down the strings using the thumb, index, middle and ring finger.
From bar 5 the melody starts, the first chord is played using thumb, index and middle plucked together the melody is them picked out using individual fingers.
From bar 13 there is a chord picked then single note variation, chord piked with thumb, index and middle together, the single note typically being played by the ring finger.
