Hi sohard
Kindling is a real thing. Withdrawals can get worse in time, and so can the anxiety.
Noone here can tell you with any authority whats likely to happen. Withdrawal is unpredictable.
I do remember being very frightened I was going to die. I found lying down helped a little, even if I didn't sleep.
If you're worried about a seizure and it's really freaking you out, there's really nothing for it but to get yourself to a Dr or the local hospital.
Much better to be safe than sorry.
Other than that I hope things look better in the morning.
