Never get a pet of any kind if you can't love it, spend time with it, get it medical care and medication as needed and be able to purchase food for it. An animal needs and deserves as much as a human. They are sometimes difficult to take care of, they can be expensive if they get sick, they can do damage to your home until they learn not to.
It seems to me that you are not ready to have a pet. I would never discourage anyone but as the owner of 3 dogs, house dogs, I know how much work and expense can be involved. Yet, I still find myself checking the shelters for a puppy! LOL
