How to analyze circuits like this Analyze a circuit with two diodes and two voltage rails

enter image description hereSchematic showing two diodes across two voltage rails

I want to find I\$I\$, Id2\$I_{D2}\$ and V\$V\$ in this circuit. The diodes are made of SiSilicium. I'm a beginner and normally I would assume the diodoDiode bias and then apply KVL to see if it is true. However, I've only encountered circuits where the wire forms a loop.

  1. How am I supposed to apply KVL in this case?

  2. If voltage is the difference in potential between two points, how can I find the voltage of V if one point is outside of the circuit, therefore, outside of KVL application?
