Sparky - praying for you and your family at this awful, difficult time for you all. Suicide always leaves a sense of guilt I think, in those left behind (my own family has been touched by this, though not my immediate family). Please believe what others have said: there was nothing you could have done and you have nothing to feel bad about. Your brother was ill, and although you and others would have liked to have been able to make him better, ultimately that wasn't possible... but he died of an illness, just as much as if he had had some purely physical disease. I pray that he is now at peace and that you too may find peace in your heart as time goes on.
Lumpy - you are very welcome here. Praying for peace for you tomorrow and that whatever happens it's not as bad or as stressful as you feared.
BES - praying for peace in your household too.
MHD - prayers for your DD as she completes her mocks.
Bloomed - prayers for clarity of vision for you.
Also keeping prayers going for all, including Orchid, Edd, Oma, Lissette, PA and others.
A prayer of St Augustine
Watch, dear Lord, with those who wake, or watch, or weep tonight, and let your angels protect those who sleep. Tend the sick. Refresh the weary. Sustain the dying. Calm the suffering. Pity the distressed. We ask this for the sake of your love. Amen.
