I am 53 years old male and am suffering from MDD and GAD for last two years. The medicines I have been taking are D-Veniz (200 mg once), Prothiaden (75 mg once). Toficalm (100 mg once) and Sizodon MD (0.5 mg once). My doctor says I need to have these medicines life long as this may not be curable. Please let me know if this is curable and, if yes, what medicines I should take and in what doses.
