It is possible to suppress grief, but it is a very unhealthy thing to do, emotionally. Grief is a process that allows us to come to terms with loss, both consciously and -- more importantly -- subconsciously. Suppressing it can and likely will lead to emotional problems later in life. In addition the active suppression of grief at the time creates additional stress, not less, as one might think.
