Hi Rumble Doll
With struming you have a choice, it's either up or down. Try playing along with the track to get the beat. Try singing along, as the words will give you a clue how to play. In the case of Bad Moon Rising , I would go
G Chord down, down then (up down (quickly)) - D Chord down down - C Chord - down down - Back to G for two downs. etc
Try

for some help on how to play songs.
Have a go at "Horse with no name" very simple chords so you can focus on the struming.
After that, try any of the "Easy Songs for Beginners Lessons".
Good luck and don't give up
It's not easy playing a guitar BUT but it is worth the effort in the end.
Cheers
Howard
