You are definitely not alone. Alcoholic mother here too.
I think whatever you decide to do you should read around the forums, in the newcomers section there is a sticky up top called, what to expect and how we did it. Lots of good stickies at the top of this forum too.
You definitely need to have a good plan in place to support your decision to quit.
For now please be very careful with your health. Hard detoxing with a history of seizures is so dangerous. Take care of you. You can do this!
