where can i find sad poems of a loss aunt?

Answer 1

The tide recedes but leaves behind
bright seashells on the sand,
the sun goes down but gentle warmth
still lingers on the land.
The music stops, yet it echoes on
in sweet refrains ...
For every joy that passes,
something beautiful remains.

M.D. Hughes

This doesn't specifically address loss of an aunt, but I found it when I was experiencing grief. It has stayed with me and I read it when I need some comfort in difficult times.

Answer 2

Say not in grief that she is no more
but say in thankfulness that she was
A death is not the extinguishing of a light,
but the putting out of the lamp
because the dawn has come.

- Tagore

Not specifically about an aunt but could serve the purpose.
