Transaction failed: How to stake CPU?

When I e.g. try to delegatebw to stake more in CPU I get the following error:
“Transaction failed. Error message: [3080004] tx_cpu_usage_exceeded: Transaction exceeded the current CPU usage limit imposed on the transaction. billed CPU time (1836 us) is greater than the maximum billable CPU time for the transaction (151 us)”

Maybe it’s related to my CPU usage: 354 µs / 131 µs

Did I kill my account by having to less CPU staked?
