Triggers will always be triggers so long as the thought process behind them/memories associated with them are not processed.
Are you seeing a professional who you could call?
I agree that the meds are preventing you from processing your grief. You can become dependant on them to get you through a bad patch, that is not the best way to go.
Grief and pain very rarely overpower and overwhelm, a lot of the time after a good hard cry and a wail the energy is released and can flow again giving peace.
Have you tried journalling as an alternative to meds?
