All My Loving - The Beatles

I want to learn this song so my band can play but I don't understand the unique strumming pattern. I know the first chord is Fm would you play the whole chord, or just the higher notes? And also, the strumming sounds very bad if you have your pick at an angle. How would you strum this?
Hi If you still need the strumming just let me know and I'll post it in my blog in my profile also there are other strumming patterns in my blog if you need them so check them out.
