How To Overcome Addiction To Phensydil Syrup?

Doctor I am costuming 2 bottles of phensydil syrup or sometimes tossex for more then 4 years. After my divorce. Now to remain active in office I take it. Otherwise I get depressed because of my marriage. My age is 39 yrs. I am bachelor in civil engineer and govt servant for last 13 yrs. I want to leave this syrups permanently. I tried to leave many times but then it comes in my mind that I will not any more so what is the point if I take or not. I know maximum I will die .and for last 8 yrs after my marriage I have got frustration in my life after having everything. I don t want to go in rehabilitation center. I wanted to leave by staying at home . I take 1 or 2 bottles of need ras and aamla ras everyday so that what syrup I consumed everyday should go. I am spending almost 10000 per month for this bad habits. Please give me suggestions or any medicine due to which I can leave this. Thank you.
