Psych me up for a possible promotion

[Anonymous]

I've had a couple conversations with the CEO about being promoted to a vacant leadership positions at my office (his suggestion based on input from some senior staff). I'd pretty much be in charge of this location. It's been vacant for a while and we really need someone in that role since it's now clear things are falling behind administratively and we are losing out on additional opportunities forlack of leadership. Caveat is that I'm a technical worker bee. We have technical managers senior to me who just don't want to do this job and want to do their technical thing and lead their teams. I've been here for a number of years and like my job and organization and have helped out with all sorts of things in top of my direct work so I know how the organization works and what's needed on some level but from a bottom up perspective. It's a great opportunity but I can't help but revert to the imposter syndrome. It would be a perfect career move and what I envisioned say 5/7 years from now. I would have mentoring help from some senior staff I'm close with but it's definitely throwing me into the deep end first. it's going to be so much work and I will be visible and responsible as opposed to being that person at staff meetings asking the uncomfortable questions of the higher ups. And yes I'm a woman which has its own complications. There are no women in any senior management roles at my company (400 people). So I would be the first and the youngest.
Help me get my jitters under control DCUM. I do have a vision for this office and can get us there with buy in from the staff and some process tweaks.
I also need to come up with what to ask for in terms of new compensation since I don't want to get screwed on that front and I hate those conversations.
