Baby blues?

Im not sure if i ha PPD or not....

But I can literally go all day and so far ive gone 2 1/2 days without eating then my hubby forced me to eat.... I spend most of the time in bed with my babies (i have a 2 year old and my newborn i bring their diapers/snacks/ water/juice in my room in a mini fridge) i still cook meals for my hubby and son, i pump milk, i sleep, and repeat... i just feel like i dont have energy to do anything, and mostly i dont wanna do anything.... my husband has been sleeping in the living room and ive been in the bedroom with the kids (they have their own rooms but my sons been attached to his sissy since day 1 and my daughters a newborn who sleeps in her bassinet while her 2 yr old brother sleeps in bed with me... i just feel so isolated and alone, i talk to my hubby about it but i just feel like I burden him when i need help to the point I just don’t ask for it anymore....

What should i do
