I feel ya, man I had a withdraw from stimulate type drugs, I was taking them all the time, then they got boring but when I tried to quit I was sad and angry at the world, I took a knife and sliced my poster of black sabbath with the song name "snowblind" on it, I burned it, then slept, for 12 hours. I woke feeling like a fat person had just got done using me as a fucking pillow, so I said fuck this so some pain meds and just went back to sleep again, woke up, this time I felt like all of my emotions were sucked out of my body, like Luigi came in and just fucking sucked every last thing that makes me a human out of me. I was a lifeless deflated waste of space for the next few days, it took another 3 for me to be back at 60 percent, it took another week for me to feel normal again, so if a opiate WD is anything like a cocaine/stimulant WD, then be prepared buddy.
