I got talked into getting a bridge and was not told that I would end up losing perfectly good teeth. What can I do?

Can the front of this first tooth on the bridge be shaved down in the front and the back? It's very round and thick. I'm absolutely miserable and I'm suffering panic attacks every minute of the day. Unable to function. Want to pull it out of my mouth. Also, can I get this whole thing taken out of my mouth and get caps put over the two teeth that were good in the first place? Thirdly, how do I go back in time and get my good teeth back?
