SUBSTANTIAL seroquel cut in July

Hi all, my FORMER prescriber cut me off seroquel at 15 mg in July. August and September were manageable but October until now has been a nightmare. I'm extremely sensitive to noises and commotion and I'm struggling to just eat, shower and take meds. I don't socialize anymore and I'm scared to death of driving. Do I have protracted withdrawal? I refuse to go back on, so please no suggestions to reinstate. Just looking for some suggestions on how to make it through this. Also, my only saving grace right now is I sleep a solid 9 hours a night, so I know my nervous system is hopefully resting some.
