smoked spice and dont feel like my self

Hi I'm 18 years old and I haven't smoked spice that much in My life. Maybe like 3 times every two weeks, only probably 20 times in all. I smoked about 36 hours ago and freaked out.. I thought I was in a dream and kept thinking I wasn't real, like there's the real me that people can see and then there's another me locked inside my brain.. I need some help please because I dont want to live like this forever, I loved my life before this incident and just want things to go back to normal.I'm only 18 and have good grades and very athletic and good at sports so o have a future. Just somebody please help,and advice is helpfull on what to do and how to get rid of this. I haven't told my mom yet because its only been 36 hours but if I keep on feeling this way then I will tell her so I can get a doctors help.. please.. anybody with any advice please help me.. and this was not real weed, it was online spice or synthetic marijuana.. please help. Thanks
