IF this isn't right then please tell me. Sounds right to me. 

The main riff doesn't look right, but when you play it you can get the rhythm down. 

E         G E G 
Things are bound to get better, someday you'll be happy

You're gonna find true love, and start up a family
 A     E  A       E             A                      D      
Bulls**t, f**king bulls**t, nothing aint never gonna get better no how

Ya gotta look on the bright side, take a walk in the sunshine
The light is on your side, evil are good???

Bulls**t, f**king bulls**t, nothing aint never gonna get better no how

E                               A          (back to main riff)
If it's gonna rain why don't it, f**king rain
E                                 G        (back to main riff)           
And if you gonna leave me darlin, go and leave

I'm tired of living on nothing, I'm tired of longing for something
Dead dog in a trashcan, man it's all i can find

It's bulls**t, f**king bulls**t, nothing aint never gonna get better no how
Ya gotta look on the bright side, take a walk in the sunshine

If it's gonna rain why don't it, f**king rain
And if you're gonna leave me darlin, go and leave
Ya gotta look on the bright side, You gotta look on the bright side
You gotta look on the bright side, cause people are good
Bulls**t
