My dad with alzheimer's
so i loved my dad ever since i was a baby, my mod died when i was 5 and he was the only one there for me, i am 29 years old now and i just found out that he has Alzheimer'z disease, he has forgotten everything we have done together and is now turning into a vegetable, he is also having small changes in behavior,i know he might die from this and whenever i think about him i just breakdown and cry out of nowhere, and i am almost crying right now writing this post. is it normal?
