I woke out of bed shaking with a fast heartbeat and dry mout

Hi... I am 21 years old. I have had an overdose with tylenol Pm. I did this about 1 year ago. I was almost dying but they gave me some black stuff at the hospital and I threw up alot. I was hospitalized for a week. They ran test and found all my organs were saved. Ever since this overdose I have been very tired. I dont smoke or drink. I do not work so I am home most of the time. I tend to get rapid heart beats almost everyday. Dry mouth occurs when my heart starts beating out of control. One night I woke out of bed shaking with a fast heart beat and dry mouth. I was really scared but did nothing about it. I have not been able to go to the doctor because I have no insurance. Please advise on what it could be. Thank you Please email me ***
