Can I sue my employer for harring me into a job transfer?

I was made to feel that if I did not take the job transfer my job would be in jeopardy. I am the sole bread winner for my family and could not risk losing my job. Since making the move my old home has been forclosed on, my savings are depleted and my credit is ruined. The company offered no support other than a 90-day relocation policy during this last two years. The DVP who pushed me into this has a history of bullying people which upper level managment is aware of. I can't afford a lawyer and am seeking a response from someone with HR and/or employment law background to clarify for me if my employer violated an employment law in my situation.
