Please tell me the newborn trenches get better

Please tell me some positive stories about getting through the newborn trenches quickly…my son is 3 weeks 5 days old and tonight he cried for nearly 3 hours on and off. Would only calm down when nursing. My whole body hurts.

Every night I say “tomorrow will be better” but the days just keep getting worse.

Please tell me the colic and trenches end soon. Did anything help your colic babies?
