I really appreciate your post, trying to decide what to do with your puppy....
Apart from the obvious issues in potty training, the puppy will only get limited social interaction, so her/his good and bad habits will magnify. I think it is time early on, to consider placing the yorkie in a new home.....then when you life settles down a bit,...maybe working closer to home, or out of an apartment....later, get another puppy. But unfortunately now is not the right time, or fair to the puppy.
JMHO
There are MANY YT people here...that could/would like to buy your puppy.
Do you have pics? and where did you get the yorkie?? Breeder? Pedigree? Maybe the breeder has someone in mind...if you have that kind of relationship...
Best wishes!
