Short tempered mother

I just gave birth almost 2 weeks ago via csect, im still in pain and since im a first time mum, im still not able to figure out what baby wants. Cause he keep crying non stop and never sleep at night, altho we’ve tried everything. And he’s always hungry even after 2hr feeds. And due to my temper, i get tired and tend to scold baby cause i cannot figure out what he wants and he wont stop crying like someone beat him or smtg. And i feel bad for him for having a mum with low patience. He dont deserve the scolding as he’s just a baby and he’s also still adapting to the world. I always call myself a useless mum cause i am 😔 I didnt expect motherhood to be this bad. I always hear people say their baby atleast sleep everynow and then or sleep thru the night and only wake up for feeds. But mine even after feeding him, he’ll continue crying. He’s on full formula, 50-60ml per feed. Because of this, and lack of sleep (only had 1-2 hrs of sleep per day), i tend to get angry at everybody and always cry. I dont know whats happening to me, all i know i no longer know my old self. I feel like im a whole different person after having the baby. #firsttimemom
