Audio - nights were the worst for me, and specifically the 3rd night into the fourth day. Hang in there brother. Have you tried a hit bath yet tonight? If not, that might be something to try. I know it sounds stupid, but a hot bath would help me more than prescription meds sometimes.
I would have messed up thoughts like that all the time during withdrawal. "This **** is never going to end...I ****** my brain up permanently...I just want to drop dead, etc., etc." Whenever it got that bad it would tend to ease up not long after.
