Finding things difficult, newborn and toddler

I have a 2 year old and a week old baby and finding things difficult! First of all my toddler has turned into a nightmare and I'm sure she hates me now 😢😢 this makes me cry every day!

Tonight my toddler decided to wake up at 1am and be wide awake! We brought her in our bed but with my newborn screaming for a bottle and then screaming when I burn her my toddler wouldn't sleep. My husband has gone to sleep in her room and iv come downstairs and sleeping on the sofa with my newborn.

I love my newborn to pieces but I really feel like iv totally changed our lives! Will this ever get better??
