I was diagnosed with depression 3 years back. From then on I'm continuously on medications. Initially I thought depression was due to exam stress I had. Later I realized that it wasn't because of it. Till today I fail to know the cause for my depression. After taking medicines with the advice of my psychiatrist I stopped my medications. Within 2 months I started having relapse symptoms. I have tried taking counseling. That dint help much. I have a great support from family and friends. As such there is no problem going on in my life. But I don't know why i am depressed and that ends up making me more depressed. I feel the urge to get out from it. someday I have impulsive thoughts and the urge to commit suicide. There is this weird feeling of emptiness. I can't believe my life has changed so much in past 3 years. It feels like a complete new me I can't even recognize. I have stated taking medications again that is venlor 75 mg. How long should I take medications? I am tired.
