My question is regarding Vdb.
for pos flow of charge

Vbd = -Vdb
and
Vdb = -VR2
so Vbd = VR2.

This means that the current flowing from point d to point b gained potential energy. However the flow of charge from d to b are electrons and electrons lose potential energy as they move from lower to higher potentials. So when I look at it in that point of view
Vbd should be equal to -VR2.

Can someone clarify to me why I am wrong.

Electrons are negatively charged, and flow in the opposite direction of the current.
