Can you only deal with one depressing event at a time?

When I was 14 I lost my grandpa, grandma, and aunt, who collectively had played nearly as large a role in raising me as my parents, all within the span of about 7 months. right around the time they passed away, my parents were both diagnosed with cancer. my father's cancer was terminal(Mesothelioma). my mother, however, had liver cancer, and remission was still possible. after I had turned 15, they both passed away. my father went first, and my mother passed about 3 weeks afterwards. I had to go live with my aunt, which caused a host of other problems for me(Imagine 2 depressed people, one with the raging hormones and mood swings of adolescence, and the other with menopausal symptoms, and a generation gap of nearly 40 years). We argued constantly for the 4 years that I had to live with her. Now I am 19 years old, and I have moved out. however, I'm now starting to miss my parents for, what I believe to be, the first time. I never really grieved over them while I was living with my aunt. Is it possible that my mind pushed grieving for my parents to the back of my mind while I struggled with my aunt? lately I have had many bouts of crying, extreme loneliness, more frequent panic attacks, which started around the same time my parents got sick, and I generally don't get any enjoyment out of the things that used to make me happy. I saw many social workers, psychiatrists, etc. while I was living with my aunt, and I had been diagnosed with major depression, and I am now showing similar symptoms. Please cite your resources, and if you have any advice for dealing with depression(besides taking medication, because apparently the psychiatrists around here don't believe in medicine) please post that as well. Thank you.

I didn't have half the traumas you seem to have had, but I had an entirely different sort that consisted of unloving parents, poor academic performance due to sudden jumping of 4 standards, an emotionally draining love affair, persecution by strangers who should not have had anything against me, all these caused a terrible psychological outcome resulting in a major psychiatric upheaval that was first diagnosed as schizophrenia, and later as manic-depression etc. I was on heavy dosages of psychiatric drugs from 1983 to 2007. Gradually things started improving from 2006 onwards and for the past 1.5 years I've been free of all drugs (it was reduced gradually). I know, so far as I'm concerned, it was due to a series of spiritual practices that I adopted since 2004. But I won't be able to prove it, nor am I certain that what worked for me will work for you. however if you you are interested in knowing the details, feel free to e-mail me.
Best wishes
