It sounds like you have hidden your addiction from your family - like I did - and MUCH of the anxiety of the entire situation comes from shame.
13 months may feel like a long, long time, but it is not too late to free yourself in the sense that the great struggle most addicts face isn't so much the physical withdrawal as it is the deep, deep depression that follows, and the duration of that depression is often in synch with your duration of use. There are thousands of opiate addicts out there that used heavily for DECADES. Their brains' reward mechanism, the natural "feel good" chemicals, have been co-opted by opiates, and it takes time for those to heal, for you to feel "normal" again.
Suboxone saved me. Find a good suboxone doctor. They will NOT talk down to you, judge you. They have seen it all, and simply want to help.
Best of luck, you are not alone. Please find help right away.
