I'd hate to see you give up your dog unless you really felt it necessary. As you said you're doing the basics for him even when you don't do the basics for yourself. Do you feel a bond with your dog? Does his company make you feel better? You didn't say what breed he is - big or small. And you said you recently moved out - maybe you'll feel better in your new living situation. Maybe when you don't have much energy you could just spend time sitting on the couch with him and petting him. I have 2 cats so I don't need to take them out for walks but much of our time together is with them sitting on my couch with me and I let them sleep in bed with me which I find comforting. Dogs are usually so eager to please their guardians - just do the best you can and if you're bonded with him I hope you're able to keep him.
