Only you know exactly what you need to do in order to get sober. Going to inpatient might allow you to get away from any household drama for a month, but you'll eventually have to go home sometime.
Counseling is a huge tool. I am 9 months sober from heroin and I never went to inpatient. You just need to decide that you want to be sober more than anything else in the entire world and to do whatever it takes. Whether that is counseling, AA meetings, many doctor's appointments, out patient rehab, inpatient rehab, reading books, giving away your car keys..whatever YOU need to do it then that is what you need to do.
