And for anyone still considering SRE: when interviewing, ask how incentives/bonuses/promotions work for software engineers and how does that compare to SREs. A lot of promotable activities for SWE (shipping new things constantly) have negative value for an SRE role, since continually changing infrastructure ensures on-call never develops mastery of those systems.
Back to the OP, I raise a glass to your sabbatical. Most SREs end up needing a healing period from repetitive stress injury (AKA burnout).
If I may offer some completely unsolicited advice, don't put too much pressure on yourself in the next few months. People who gravitate towards SRE work tend to thrive under short-term ambiguity and emergency/urgency. However, long/medium term ambiguity without a clear productive goal can quickly feel like a crisis. OP mentions this in closing, so I'm rooting for them to rest and "sit still" for a bit.
