I'm not sure it's about suicide necessarily. I think es89 is right about it being about a person who spends their days with their head in the clouds ("My feet never touch the ground"). The swinging man doesn't want to bother with reality and its pains, so he looks to get high or drunk, etc. to take his mind off it all. He's living in his own little world, waiting for someone to snap him out of it ("Now if you love me, you'll cut me down").
