Oh Mera. You can come back. You will come back. It is never, ever hopeless. Never. There is always a way. There are incredible stories right here on SR of people who thought they had lost it all, and rebuilt their lives.
You have your kids, you have your health. You can find a new job. Don't let the way things ended at your old job derail you... there could be many reasons why they might have wanted to create performance issues. You can come back from that.
You will get your licence back, then you can work out what you need to do about the car. That was a mistake that you made, driving after drinking, and you should own that mistake.
Then you can come back from it. We have all made terrible mistakes here on SR, and we know what it's like. We are all alcoholics here.
A plan, Mera. You need a plan. A plan to make sure you don't go back to the booze and a plan to come back from this.
You can do it. Keep posting here, and keep close to SR. With the help here, you will come back.
