The only fact that you went two days without it shows your will to quit, and most important, shows you can quit.
I totally get you being hesitant to go impatient, but it will be for the best. I really thing so.
You need a full stop, a kind of stop you won't have at home with 3 kids.
Eventually, you will have to cop with it again, so you have to rest and think in order to re- focus.
It sounds like you are at your limit, the last thing you need now is to home detox, can't bare life and relapse, detox again, relapse again... you don't deserve that.
Let alone you are doing full spoon shots of cocaine, it is a very dangerous addiction and I hate to hear that you feel as you could die, but you might be right.
As Nurse said, run to impatient detox.
Get healthy and strong for yourself, for your husband and kids. Give yourself yet another chance. Get help and get advise, let people take care of you.
But you need to make the first move, the first step in the right way. It is like the poet said "Walker, there is no path, you make your own path by walking"
Do it now, Surferchic.
All the best, girl.
