Hello CGD .......
I am a firm believer that at least some types of animals can be a huge boost to our emotional well-being. They do take some time, some cost and some love though.
What Karen just said makes sense - at least as a starting point. If you were to volunteer at a shelter for animals, you could be of great value to the animals - and they might help you develop a relationship with an animal, that might be adopted at a later date.
Even if adoption doesn't happen, you would be in a win-win situation with the animals in need of help and love.
Good luck to you on your decision.

P.S. - Gizzy is my best friend, a 34-month old Samoyed ... about a 45-pound dog full of love.
