If it makes you feel any better, I'm on the same boat. My skin feels like it's constantly crawling, my stomach feels like a colony of ants are building themselves a little home with my innards, I feel like I'm butt naked in a blizzard one minute, then in the earth's core the next. I'm puking everything I eat and I can't sit still for one minute. Minutes seem like days, as if time has ceased in its place. I somehow....somehow made it day 6. I don't feel any better but I know I will with each passing day. It's mind over matter. That may seem like worthless advice now, but just think about a life without opiate dependence. It's freedom in my eyes. What eases my mind a bit, as fucked up as it is, is that there are people out there who are living in way worse conditions than I am. People who would give their limbs to be in my shoes.
Not trying to pry into your personal life (which is kind of funny given the situation), but do you have enough money to pay for clinical help? Suboxone can be a lifesaver for someone like you who is dependent on such a strong opiate.
