Feeling very ugh...

I think I just need more friends... my husband is barely ever home my husband mom has our little tinys which is fine -we both had to work today- but lately he barely talks to me and I had a really rough day -personal stuff feeling alone.. so I told my husband mom what was wrong and she could tell I was crying she thought me and him got into a fight I said no I couldn't say anything but to hold our kids and cried she asked if I needed my husband I looked up at her and said yeah I always do as he's my husband but I can't as he's working. And she said it's ok I'm her family to she told me she'll keep littles until Monday to be with you I said thanks but you don't have to I can take them home she refused I guess my mother-in law is amazing😍 but I just can't shake this -off feeling I think it's just cause of all the changes lately -having our kids me going back to school and changing my major my husband works 12+ hours daily so I'm with littles all by myself with not a lot of help + I'm working I have mom guilt idk maybe postpartum depression someone please help me talk to me ☹️
