I have tried many antidepressants and always come back to Zoloft/Sertraline. It is well tolerated by the majority of people and when combined with Wellbutrin can be extremely effective.
I am sorry for your loss and I hope you take your Doctors advice. I used to take 100mg of Zoloft for many years and cut my dosage to 50 mg. I think that is the smallest dosage it comes in.
The stigma of depression and anxiety has finally been lifted. Many athletes and everyday people have been coming forth with their stories.
Good luck to you.
