It would help to read the chord shapes giving you trouble. I suggest a two pronged approach if you really want the song.

1. Spend 3-6 weeks just working on the chords. Not for an hour a day, but a manageable amount (read: not thinking of kicking the dog). Consider substituting a different chord shape for any that really seem impossible after a week. There are many, many ways to play each chord - not right and wrong, just different.

When the chords seem easy played one at a time start to practice switching between two chords - obviously in the order they appear in the song.

2. Then start to slowly work on the song. It's a great tune, but it's been around a while and it will wait another month or two for you to get comfortable.

Everything gets easy when you've done it enough times. If it's not easy yet you haven't done it enough times. You can get frustrated, but it won't help you get to "enough times." Understand the process and be nice to yourself.
