Hard labor

I have an older child, and her labor was fast. My son came 2 days ago. It was a very rough hard labor on me my body's severely sore but I'm still managing. I love my children. I love my newborn. It's been almost 10 years for me for taking care of a newborn so I'm re learning everything but patient and eager to learn new stuff. However since I got out of labor Thurs I have not slept. It's not a mental health issue. I tried to sleep last night was in severe pain and trying to sleep and my partner got mad and said I wish I can sleep too so I got up and took care of him and then he did it again a few hours later so I got no sleep and got up cause he made me feel guilty. I was up all day with him wen my partner went home to take a shower and hangout with his dad for 4 hrs. I was already sore and not feeling well but I battled thru for my son. Come to 9pm tonight and my partner was taking care of the baby I went out to nurses station to get more bottles and I fainted and they all evaluated me found that my epidural site is swollen and it's cause I haven't slept and they're offering me atarax cause they think it's anxiety it's not I'm just beyond exhausted and my body needs time to heal even it's for an hr. They said they'd bring a chair and never did and I'm a fall risk so I can't get up n they don't pick up the bell. My partner asked to take a nap for 2 hrs and I said sure and I kept the baby calm and okay the whole time and I'm battling feeling ill in between and the baby wants me close to him so I'm just letting him hold my hand. And i also feel bad and not well supported at our labor n delivery unit they never come back to check on me hardly. And I have no one to talk to cause he can lie and deem me depressed or anxious and then I'll lose everything. Idk maybe it's me maybe I'm a bitch I'm grateful for him and his help so far but I just need a second to rest so I can feel physically better to properly help and take care of my son.
