Postpartum depression ?

I’m a first time mommy my baby is a week old and 1 day so I’m 1w pp I don’t even know where to start or even how to explain how I’m feeling but I’m gonna try my best ... ever since my baby was born I couldn’t sleep and I’d cry constantly. I love her soo much more then anything 😢 I figured I was crying so much bc how much she meant too me and I just couldn’t see myself without her 😢 once I got home from the hospital that’s when I started to feel bad for myself & how I looked I have not touched my hair in almost 2 weeks literally I haven’t got dressed I haven’t felt good about myself at all .. I gained so much weight . I’m always crying now like all the time.. I feel like I won’t have my life I use to have no more I feel like I’ll be stuck in the house being depressed.. I love my daughter and I wouldn’t trade her for the world I didn’t realize how overwhelmed I would feel tho 😩 I’ve never had such big responsibility. I have her dad but sometimes I feel so alone. I’m also just so paranoid like I constantly check on her, i can’t leave her side most of the time I barley eat anymore I don’t even have a appetite anymore .. I feel so sad most days and it’s hard to talk to my boyfriend about it bc then I start crying non stop and can barely talk . I also feel like I don’t wanna be bothered by anyone I don’t really wanna talk to people anymore I feel so distant most of the time . I’m ALWAYS tired .. everyday all day long . Anyone else ever felt this way ? Could this be ppd ? Idk I’m so new to the mom life it’s all so overwhelming
