Switching brand name and generic drugs by different manufacturers

I have been diagnosed with major depressive disorder. My antidepressant is a generic that contains the same chemical as Cipralex. It is called Depralex and is manufactured in Saudi Arabia. The manufacuring has ceased. I tried other generic (Citoxal, made in KSA also) and causes me a terrible relapse. I had to get Depralex again. Depralex now is no longer available in the pharmacy. My physician suggested to switch to Cipralex. He said it is highly reputable and safe to use. I am still worried to switch, as the relapse is highly intensive if it were to occur. So how was your experiences with switching from a generic to a brand name? I have to decide what to do within two months i.e. before I consume the remaining quantity of Depralex
