Thanks for your query.
Tylenol is a paracetamol
tablet taken for fever and pain.
you are supposed to take only a single tablet in 6 hours.Taking 13 tablets would cause paracetamol poisoning
The symptoms which you mentioned are surely related to its overdose.
You did not mention how many hours ago you have taken them.
But then you consult a physician as early as possible.
can be dealt later by consulting a psychiatrist
by evaluating the cause for it and treating accordingly.
Hope I have answered your query.
I will be available for your follow up queries if any.
Wishing you good health / Speedy recovery.
