Question

how was she feeling when she lower moses in the river in a basket

Answer 1

She probably worried about him, like any mother but she was proactive. She had his sister watch him and when Pharaoh's daughter plucked him out of the river she came up and offered her mother's service as a wet nurse. So he although he was raised as Pharaoh's daughter's son, he was nursed by his own mother.

Answer 2

Sad and worried, no doubt.
