Having troubles

So i am 4 weeks pp, i have been having problems the last week and a half with a lot of things. My parents where here to help me the first two wewks then i was on my own. After they left I dropped 10 lbs in a week. I never feel hungry and when i do eat food makes me neausous. I havent had sex at all so i know im not pregnant. I sleep alright though its not consistant cuz the baby sleeps on and off. I drink like 3 glasses of water a day roughly though i honestly dont remember sometimes its like im in a daze. I do live in AZ wgere its miserably hot so it may have some part. I have been really upset because my baby wont breast feed she will litterally push me away. I was pumping but its hard to keep up now i am pretty much dried up but i dont know if its pumping, sleep dep., or dehydration. I dont know how to care for myself anymore its just about caring for my daughter and its hard to integrate caring for me. Two weeks have flown by and i can barely remember anything. I am so overwhelmed. Im getting help with her but then i relax or do house work or sleep extra. Idk how to change im so stressed. I dont feel pretty i cant fit into any jeans even though i pretty much lost all the weight i gained while pregnant, and i feel ignored because all anyone asks about is my daughter which i dont mind to much but i also hear all the time how she looks like her dad ( we arent together) and its upsetting. Idk maybe i am just petty but this is hard. My partner tries to help me but i am in a funk. I dont think im depressed im still mostly happy and i love my daughter and wouldnt trade her for the world. Just having troubles adjusting. I have never been a center of attention person at all i hate it but even how are you feeling once in a while would be nice. Sorry long post....
