Firstly understand the transition means a lot of unlearning, sometimes with parts that you hold dear to you. My advice to you is to be honest with yourself, your team and stakeholders about the same. Makes it easier on all of the folks and eases the transition.
3 Circles of X: As you start going up the ladder, your focus is on a birds eye view of three circles: Your Customers/Markets, Your Products and Your Team. You are here since you get the bigger picture and you need to help your team do all of their core functions with as little hassle as possible. I came to terms with myself when i started thinking of myself as a lubricant, and it all made sense.
Tons of people go through this, find people that have recently gone through the transition and talk your problems out. Also probably give Managing Humans by Michael Lopp a read.
Hope this helps!
