You definitely need to hire an attorney. Completing the UPS, home detention, and scram is all fine and good. However, not completing the alcohol treatment and not taking responsibility and accountability for all of these years will really put you in hot water with the Court. As a former judge, I always told defendant that probation was indeed a privilege and that the purpose of the alcohol classes was not to punish you, but to give you the tools necessary to avoid problems with alcohol later in life and avoid a repeat offense. To a large extent, it is a slap in the face of the judge that sentenced you, as well as the probation department that you have neglected this for so long. Any judge would have understood the problems with you losing your job and have given you an extension and cut you some slack. In all likelihood, the judge held a full year of jail over your head as a "suspended sentence" to make sure that you did treatment. Depending on how ticked off the judge is, you are looking at up to a year of jail for not completing probation.
The best advice is to quickly hire an attorney and get back into alcohol treatment ASAP. Then, you and your attorney can work out having you turn yourself in to the Court (always viewed much more favorably by judges than you getting picked up on the warrant). You do have good reason to be terrified. However, what is in the past you can not reverse. What you have to concentrate on now is getting into treatment. I would suggest doing an even more intensive or extensive alcohol treatment program than what you were originally ordered to do to make up for the long lag in not doing treatment. Although you can not change the past, you do have control over the present and your future. If you continue to do nothing, what reason does the judge have to show you any mercy? You need to concentrate on doing as much as possible RIGHT NOW as mitigation to have something positive to show the judge - whether a short-term inpatient program, an intensive outpatient program (they might not accept you), or a longer period of therapy. Given the lapse of time since you last alcohol therapy, most treatment centers are going to make you start over from scratch again.
As a former judge, I can just tell you that the longer that you let this go without addressing it, the more likely you are simply tying the noose tighter for yourself and really giving the judge no other alternative than to punish you with considerable jail time.
I understand your situation and definitely feel bad for you. But you need to get working on this now. Best of luck.
I would recommend having an attorney handle this matter for you to try to mitigate any potential consequences and get you back in the alcohol program to finish up your probation requirements.

As has been stated repeatedly, you need an attorney. More specifically you need an attorney who practices this type of law and focuses on these issues every single day. Before you post bond and attempt to get the warrant quashed you should speak with a DUI attorney who handles Probation revocation cases. There are things you can and should be doing before you attempt to clear this issue with the Court.
