Hi ejb, your story is very familiar to me except my mum passed away 10 years ago.
Its my dads 66th birthday today. He has esophageal cancer diagnosed this Feb gone, given 3 to 6mths to live
Dad was always a very active man, very rarely drank alcohol, never smoked.
Its hard to watch him struggle to get out of bed in the morning and he tires really quickly.
Lately he angers quickly and easily about little things, swears a lot & seems to direct most of his anger towards my 13yr old son who is hurting & can't understand how his poppa can change so much. I have spoken with my dad about this, we both cried, he apologized said he loved us & said he would not to do it again. He was just feeling frustrated, scared & angry.
I feel exactly the same as he does, but im feeling helpless watching him struggle to eat ( only has soup/juiced food now) all I can do is be here for him, to help however & wherever I can.
All my life my dad has been there for me & my family & I love him so much, it hurts.
Treasure each moment & don't sweat the small stuff. I wish you all the best on this journey with your dad.
