What should I do with me?

After having been unceramoniously retired in May I have found myself being mostly the hospice caretaker for Ole, our 17 year old Shihtzu. He's pretty much deaf and blind. His rear right leg is quite lame and we've been treating him for painful ulcers on his eyes due to low tear production. He still eats and drinks and lets us know when he needs to go out but you have to be quick. This is a day and night job. We take turns so we can get some sleep. I guess it gives my life purpose but the day is going to come when he is gone and i will need to find something else. No way am I going back into the workforce. I am done with it. I'd rather die. The last five years of work i had no say in what I was doing. I'm finally free of it and yet. I'm held captive by something I love.
