Find DC current through the diodes

I am trying to perform the DC analysis of the following circuit:

Since we are performing the DC analysis, the ac voltage sources will be grounded. I have drawn the schematic when AC source is grounded. I am not able to find how the current I will be divided between D1, D2, D3, D4. Please give answers in terms of I. (Please forgive me for my schematic diagram where I have placed nodes in place of arrows)
