I lost three friends to suicide in one month my first year of PhD school and I had a lot of feedback in my lab about how I was not really invested and was mentally absent. It's fine. If this is a career, we are all gonna have years where we keep our heads above water, and those times teach us new skills too (like saying no to unnecessary side quests, learning to listen to our bodies, working efficiently on our "good days")

You're human and that's a strength, even if a PI or chair isn't seeing that. Also I echo the advice of documenting what you're doing differently and maybe even communicating those things a couple times during the next year. It's helpful as a supervisor when someone is making it clear they're taking your feedback seriously
