Is this postpartum depression

So I’m not sure if what I’m going through is postpartum depression but I feel so sad everyday. I cry at least once a day and I’m no longer happy with my boyfriend. He’s an amazing guy but I’m just not happy and I don’t feel attracted to him when it comes to having sex. To me that’s like another chore rn , i don’t want to tell him that because he’s going to think i want to leave and right now im not sure if that’s what i want. I’m also not happy with the way I look, I feel disgusted when I look at myself naked. Now the reason that I’m not sure if it’s ppd is because I don’t get angry at my LO or anything like that which I know most women do. I’m a ftm and a sahm.
