Stranger in my skin

I feel so sad and miserable in my body 😔 I've felt like this for years, and over the past year its just gotten worse. I was already heavier than I wanted to be, and then I got pregnant and it made it worse. I'm now 8 months post partum and I'm the biggest I've ever been in my life. None of my clothes fit correctly or comfortably, but I'm a SAHM so I don't have money for new stuff. My fiance doesn't understand how shitty I feel literally every day and every time I ask him to buy me some new clothes he puts it off 😔 And honestly the worst part about all of this is my boobs. I wear a DDD and I hate it so fucking much it makes me cry all the time. They're just big and sag so much. I have like no muscle in them at all so they just droop down as far as they can possibly go. I've wanted to have a breast reduction for YEARS, but that surgery costs thousands of dollars that insurance won't pay for, so I know I'll never have it. I feel like I'm doomed to live in this body that I hate for the rest of my life and its so frustrating. I feel like I want to jump out of my skin and run away, and its so frustrating that this is the one thing theres literally NO way to walk away from. I'm so sick of living in a body that I hate. 😔😔😔
