Simply put, no. In fact, it seems impossible. What we know from psychology about suicidal behavior is that the person is not in control of their own actions.
For a matter to be sinfully grave, one would need to willfully do that action. Therefore in the case of suicide, one isn’t sinning willfully.
It’s important to note that at one time the church did deem suicidal behavior as an action that would merit hell. After careful discussion with the modern psychological community, the church proclaimed their teaching in a new light. This is a great example of how the Catholic Church remains in dialogue with the world, especially with the scientific community, always learning and evolving with modernity.
