Im surprised you have complaints about the absence of a bridge. I very seldom use one and no flak yet.
I believe you should try to concieve of a song as a complete project before contemplating about whether a bridge should apply or not. It isnt complicated, but it is part of the structure of the music. If the verses are samey or there are many, a bridge can break things up and at best be very dramatic.
They are by no means essential or clever. Offhand, I cant think of any Dylan song that uses a bridge. If you want to employ one anyway, then listen to some songs and identify what bridges you like first. They are typically 8 bars long and occur after the first two verses and have a different melody also. If I explain it poorly, tell me!
