First, do nothing while you're so depressed. Try to think what to do while in a relatively positive mood. Check the Net for advice and get a book that outlines what to do.
Call several attorneys and see which seems the most candid and the best fit for your situation. Their fees may vary widely.
Your guns will have to go, in all likilihood. Depending on state laws, you may be able to keep one or more as part of your homestead. I think Texas allows two firearms. Check that homestead exemption, if any, right away. You may be able to retain more than you think.
I recall that a well known gun writer went bankrupt some years ago when his livestock business failed. It can happen to many, and I considered it at one time when out of a job. I did research the matter to a considerable extent.
In your case, you will have to balance the strain of a bankruptcy against the hassle of bill collectors constantly hounding you and maybe suing for debts that can take what you own, anyway. In view of your heart attack, that hassle may trigger another. You don't need that! Ask your doctor about the risk, but I bet it's there.
Many famous people have had to take bankruptcy. Don't let the guilt and strain ruin your health at this critical time.
Immediately, learn what the federal Fair Debt Collection Practices Act will allow collectors to do. Many (most?) will routinely lie about their power and intentions. You can send them a notice to Cease and Desist letter, and can tell them that if they do persist, you will complain to the FTC and to your state's atty. general. However,that may trigger immediate suits, so ask a lawyer who specializes in such issues.
If your doctor will give you a letter stating that collection efforts may imperil your heart, sendng a copy to each collector may cause them to ease off a bit, fearing liability if you do have complications that could be laid at their door.
I was told that once you arrange to file for bankruptcy, the atty. handling the case will notify collectors, and that they must then cease activity. That alone could save your life, if stress is a factor, and I'm sure that it is.
Because this is such an embarrassing issue,I don't know if anyone who has been through it will post here. But it happens to a lot of perfectly good people who hit a run of really bad luck.
I will pray that you find the right solution and that your health improves. I trust that others here will join in that effort, even if they never tell you. May God bless and protect you at this awful time, and restore your health and your hope for a brighter future.
The sooner you learn where you stand and what you can keep, that is progress.
Nothing in this post is intended to represent actual legal advice, and it should not be construed as such. I am not a lawyer, just someone who went partway down the road that you may have to travel. But the news may be better than you fear, once you research the matter.
