You have already started the best thing possible - reaching out and speaking up! Additionally, like some of the ppl have suggested, take up any physical activity to take out the stress. I would personally recommend yoga and meditation, they can work wonders. I have had some amazing yoga teachers who will lend you an ear and offer holistic advice and guidance. Also if you are on the East Coast, the winters and snow can be depressing for some people. I used to get out and get some sun to beat the winter blues. Take care and continue to reach out if you need more help.
Unfortunate, but real state of affairs in the so called "India Shining" story! Corruption is ingrained in public and private offices. And my biggest concern is that it's become a way of life and people are indifferent to it.
