APM/PM who switched to Estimating

So I work for a really large GC along the Southeast. We do only Heavy Civil type work. I am currently in Project Management with 10 years of experience. I was asked today my an executive what my feelings are on switching to estimating. They told me I get shit down and have performed above standards in high stress times.

For people that have made the switch. Do you regret it and is it as stressful as the field?
