Edwards Peter: Suicide—whatever mental/emotional problems induce some to commit it and which might even mitigate its culpability—is objectively a gravely evil action (CCC 2280-2283) and may never be licitly chosen. When committed in a sacred place such as a church or shrine, suicide effects the “violation” of that space and divine worship (as opposed to personal prayers) may not be offered there until the place is rehabilitated in accord with canon and liturgical law (1983 CIC 1211, olim 1917 CIC 1172; see also 1983 CIC 1376). More on this here.
