postpartum depression with a colic baby

I'm honestly so depressed. My daughter is 7 weeks old. I don't get help from anyone. My SO is in deployment for a year of no contact. I just can't do this anymore. My baby is always fussy when she's awake, she's not even enjoyable. She never sleeps and when she does is for not even 5 hours. I'm running off of no sleep and no food because I don't get to seek or eat. I'm lucky if I even get to shower or do any cleaning. I hate this new lifestyle and I can't do the constant screaming and crying anymore. I cry all night because of her. I panic when I hear her cry, I can't do it anymore. It's gotten to the point where I am getting aggressive and angry. I've never hurt her but I'm afraid i will one day if this gets worse. I'm getting impatient and very angry towards her, I'm starting to resent her. I need a break but no one helps me. I just can't do this anymore idk what to do, I need help.
