This answer is informational only and does not create an attorney client relationship. I am not expressing an opinion on the merits of your case based on the facts above. My answer to this question might seem curt or mean. My job is not to be your friend, but to tell you the truth. Sometimes the truth hurts. You don't want a lawyer that tells you everything you want to hear, pats your head, rubs your belly, and gives you a balloon. That lawyer is not doing you any favors. This is not legal advice. This is free. You pay for legal advice.
