First got a big ole hug for input
Second - I have experienced all of those symptoms and had no baby .... for me it was Vitamin B & D deficiency ... being vitamin B and D deficient mimics a lot of symptoms of 'depression' as well as 'forgetfulness' .... and well having just given birth your body is likely still adjusting to having 'shared' so much of its nutrients with babe plus women often taken the supplements WHILE pregnant and than think they can stop afterward but in reality you are likely still using more than 'normal' while caring or breastfeeding baby .... if you are not taking Vitamin B or D supplements I would try that and see if it helps alleviate the symptoms - double check with the pharmacist which are best if you are breastfeeding as I am not familiar with what gets passed on to babe or not in regards to this!
