IM resident struggling IN critical care [ICU Rotation]

I get panicked sometimes by emergencies. My role as snr in wards is top 10 percentile. But when it comes to ICU setting work environment I struggle. ICU Attending gave feedback that I am too dependent on them for A/P. Main critique is i bother them too much. I feel abit diff from wards because in wards I consult subspecialities who help guide plan. Over here they do not want any consults without first referring to them. And the threshold for consult is very high in ICU. I want to improve genuinely. I saw the Marino book but its just way to lengthy. Can anyone guide me with YouTube videos or like brief book that covers the basics well. I feel in medicine once basics are strong rest can be covered by daily chart review and uptodate reading.
