Honestly. you should first of all, if nothing else, because it is very easy, inexpensive and very very safe, start drinking alcohol. Drink heavy and drink often.
It will not cure anything at all. But it will make life a lot better for you in any short term you can think of. I guarentee you that.
Next, you need to figure out how to get some benzos. Be safe, you will get addicted to these. Use alcohol as a substitute to taper, and alternate days where you drink or do benzos. That slows the tolerance build up.
This business of living, it is really tough, so don't be so hard on yourself.
