Ppd insomnia?

I recently weaned from pumping, I was not able to breastfeed due to my son having a lip tie but since I weaned I been having insomnia and it is really bad! I'm not sure if I'm depressed or is just the hormones since my period also just returned. I have always been a great sleeper so I am not sure what's wrong. I just want to sleep 😴 anyone else experienced this??
