People have given you great advice on working on the issues you have, if that is something you choose to do.
As far as your original question though- I think it is time to call it quits when an animals quality of life is suffering. If you don't have the time to exercise the dog, train the dog, spend time with the dog, etc- then maybe it is best for the dog to be in a new home. If you are too stressed when you get home, the dog will feel this and act accordingly.
In the future, I think you need to spend more time researching the type of pet you are getting and the time they require before adding a new addition to your home.
Good Luck to you and your pup.
