Reliance Standard is making me jump through hoops to receive my benefits, and I lost my house because of it.

I have been receiving LTD from Reliance for 2 years. They sent me to the Advocator Group to help with my SSDI. I have had three different “representatives” during my 2 years with Reliance, and the Advocator Group has changed names 3 times. I applied for SSDI because Reliance told me that I had to, to receive benefits. They told me that they would receive all my back SSDI payments if approved, which makes sense since that’s what I would have had yo give a lawyer of my own choosing. Now that 2 years is up, Reliance has my case under review to see if they feel I qualify for further payments. I have been asking them to do this for at least a year, but they managed to stall until my last check is due. Also, the Advocator Group said last month that it usually takes 18 months from the time you apply for SSDI to get a hearing. I applied 2 years ago, but it looks like everything is going to happen at the same time (though I still haven’t heard about my hearing date.) I have lost my house, gone bankrupt from trying to keep up with my medical bills. I had to move because I was living in Flagstaff AZ (elev. 7400) and due to my medical conditions kept passing out and couldn’t breathe. I still have those same problems and have been diagnosed with multiple heart and lung disease. I can’t stand the anxiety and think about what the outcomes will be every day and night. Reliance Standard says if I do get approved for SSDI that my checks will have to go to them? I paid premiums to them for LTD, and I paid social security for all my working life (will be 59 in August). Isn’t my work LTD separate from my SSDI? I am so confused and didn’t know to check into all these things before. I feel like I have been too trusting and naive. Can Reliance claim my SSDI (if I even get approved by either of them in the first place)?
