Anyone else feel like lonely??

So werid I feel like a puppy when my husband comes home from work just to see him. Throughout the day I feel super lonley my baby is healthy but I did have a traumatic birth ended up in c section as she was to big for me to push out I love her so much but man I can't shake the feeling of wanting to cry for no reason. She's a cluster feeder and has night and day confused. My hubby is amazing and helps out way more than he should ladies he even blow dried my fat flap so my incision so it dosent get infected. He does it all. But I dred nights as I know in a few hours he will be leaving us once again. I love her so much but I fear of doing something wrong as a FTM what if she's not getting enough milk from me what if we both fall asleep and I can't hear her cry because I'm still sleeping. Ugh I am just so lonley
