How do I mentally get through weening my child

Ileia

I’m almost 19 weeks pregnant iv been trying to nurse my 18 month old less. She nurses once during the day for a nap and alit at night . It’s been almost unbearable nursing at night sometimes it hurts and is uncomfortable with being pregnant they are so sensitive. My baby wouldn’t stop crying and I just couldn’t nurse anymore she wouldnt fall asleep nursing. I ended up letting her cry herself to sleep in her crib I got so upset I just cried too. Does it get easier? I hate to go cold turkey but it’s just too much . How can I make it easier on my baby I just feel so bad...
