Bob, I understand how you feel and would make no attempt to change your mind.
However I will say that I retired about a year ago and that,without my pigeons, I would have found the days---especially in winter very difficult.
We all need an interest to keep us going and pigeons fill the void for many people.
You need something to get you out of bed in the morning and knowing that the birds are dependant on you is all the motivation I need.
Think very carefully before you take any decisions.
