Post weaning depression?

Any other mamas dealing with/dealt with post weaning depression? I recently weaned my son- I was so hoping to make it to 2 but he kinda just chose to be done. And I think that’s kinda aiding to it. It was more abrupt than I thought it would be. I can’t even really explain what I feel like. My mood swings are awful, I’m crying constantly like I have baby blues again, questioning my worth. Is this even normal?? Why am I so sad when I should be so happy we made it almost 22 months? I did go ahead and make an appointment with my OB, but I figured this group is so supportive, I’d ask for some advice here. Even just being told that yes it’s normal and I’m not a weirdo for crying about weaning my toddler lol.

I hope you are all doing well! Your babies are all so big and beautiful! Where did our tiny babes go?!!
