hi
sorry i'm late but i saw it days ago on facebook. i facebooked you.
i am so sorry, yet what you did being there for your Mom and helping him crossover those are huge things. I think being there with someone when they cross over is one of the greatest gifts you can give.
yes watching someone die is quite the unnerving experience. it will take time within you yet you will find your peace in it. i sat with my grandmother ten years ago when she died. i held her hand, very similar situation until she was gasping for those last breaths. knee jerk reaction is to help until you realize their sole has left it's just their body shutting down. so they do not feel pain anymore.
hugs i know this wasnt' easy, and sometimes we dont' get the closure we wanted. my grandmother passed and i had alot Occupational Therapist (OT) say to her we were in our first ever argument prior to her being in hospital. well you can still say what you have to, write a letter than go to his favorite spot and let it go free burn it shred it etc.
hang in there thinking of you
