After the ferry incident, all Peter wanted was a moment to sit, think, cry and then fix things. That's what he always did when he got it wrong. He was going to be able to fix it, not everything, but some of it. Then Tony Stark shows up. Perfect Mr Tony Stark who could never do any wrong - and Peter finally snapped. Mr Stark has been a shit role model, a shit 'mentor' and he has no right to scold Peter, so he yells and lets his feelings out, and Tony has something to think about.
