Colic

How did you survive colic and until what age did your LO have it until? My daughter is almost 4 weeks and has had it since she was 2 weeks old and I’m seriously at a loss and not enjoying motherhood at all. She cries for hours and hours a day but she’s fed, changed and slept. I don’t know what to do. Please tell me it ends and there’s a way to get through it. 😢
