Analysis of The missing part of Me

Your words do not come out right,
your expressions speak a thousand.
You was suffering.
I was being selfish.

Preferring you around,
although I knew you felt helpless.
I apologise for not reaching
for the part of me that's selfless.

My vase is without flowers since you left.
It seems I had no power over your death.
I wasn't ready to have you around less,
you are the missing part of me.

Strokes took over,
followed by dementia.
The loss of your left side
then unable to remember.

I think of you daily not only during September.
I would set myself alight to put you back together.
