Quit smoking medicines. Take it or not.

Hi i quit smoking 1 year ago with the help of vaporizer also called e-cig. I started with 32 mg nicotine strength and gradually cut down nicotine and now i,m vaping only 3mg/ml nicotine liquid in a day but my father force me to consult with a psychiatrist to completely give up of nicotine. The doctor asked me "what did you feel when you try to quit smoking and nicotine" i replied "feeling of irritability , anxiety, depress and loss of focus" he prescribed me some medicine and told me completely give up anything and just take these medicine. I told him i,m already on very low nicotine strength and will gradually come down to "0" mg nicotine in 6 month time period but he did not agree also he dont have knowledge about vaporizers. The prescribed medicines are follows. 1: zauxit 20 (fluoxitine) 2: lagintal 25 (lamotrigine) 3: pinix 0.5 (alprazolam) 4: fertex tab I did not take any of these medicine because i,m not feeling to take these tablets kindly help me should i take it or not.
