Hang on in there, i went through the same thing a few days ago, ended up in hospital but they wouldn't give me anything just sent me packing with more of the drugs i was taking & told me not to be so stupid next time.
My heads still a bit of mess as is my body but you have to surround yourself with people who care & don't shut them out, i did for the first 2 days following & paid heavily mentally. Even just have them in the next room so they are there be strong each day & night as they come, but talk & keep talking open up & let it out, tears will fall in floods but its got to happen to get through, be strong!!!
