Overdose

Char🔥 • James Riley 09/09/2016 my only baby!😻
I suffer depression and I tried to take me life the over night by overdossing on sertraline 100mg I took 21 tablets and was taken into hospital... They monitored me for 12hrs then I got discharged... I'm getting really bad headaches and feeling sick and wobbly still... Is this normal or something to worry about (please no lecture I know I did wrong)
