Do I have PPD?

I love my daughter more than life itself and would die for her but she isn’t an easy baby. I wasn’t expecting having a child to be a walk in the park but I definitely wasn’t expecting this. Everyone keeps saying it will get easier but I feel like that will never happen. I’m a ftm and a sahm. We moved to a new state when I was 8 weeks pregnant so ive been all alone (besides having my husband). My daughter needs to be held constantly and if she’s awake she needs to be bounced or rocked and shushed. I’ve never seen her fall asleep on her own. Ever. Anytime I try and put her down she wakes up crying. I’ve tried swaddling, I’ve tried the rock n play, the bouncer, the dockATot, I’ve tried two types of wraps/baby slings,the 4moms MommaRoo, white noise machine, a dark room, rocking chair, waiting until she is dead asleep and nothing works. I hold her around the clock until my husband gets home at 5 and then I go to the gym for an hour to let off steam, come home shower and it’s back to holding her. I bed share with her because it’s the only way she will get any sleep at night. Everyday I feel a little piece of my sanity slipping away. I get no time to myself to just breathe and I’m starting to dread every day ahead. My body hurts, my back is killing me from walking her around, I feel like I’m losing my mind. I feel so isolated and alone with a baby stuck on me. I hate it.I can’t tell if I’m starting to get depressed or is this a normal feeling. I see all these people with babies sleeping in their cribs or bassinets for naps and night time and I don’t understand why my little girl just won’t do the same.
