I can relate to where you are. See my story here. It might give you some ideas on how I am recovering. There are many stories on here that you can get inspiration from.
The first thing I would say you must do is come clean to your family. Tell the entire story without leaving anything out. Bare your soul. It will be incredibly hard.
Then comes the recovery part, sell the house if you can and move to an apartment, move in with family if you can. Use the house equity to pay off your high interest debt. Then work your way towards being debt free. If you are spiritual or religious, believe in a higher power to help you through this . Miracles will happen. Join a GA club or attend some courses. You’ll see you are not alone in this.
Don’t take any drastic steps with your life. It is a dark place you are in right now. Many of us have been there and can relate completely. It is not going to be easy but there is a way out of this. Keep working on staying Gamble free. One day at a time. Good things will come. Keep posting your thoughts here. Get ideas, inspiration and support. There are many who have documented so much of their lives here. Please read and reflect as much as you can.
