Gosh, so sorry to hear you are having this problem with your yorkie. I don't think I've ever had this issue....maybe because I've always had more than one dog. However, I've seen this issue dealt with on "It's Me or the Dog" with Victoria Stillwell on Animal Planet and some of the advice given here is what she recommends. From watching her shows I have definitely learned that
repetition and
consistency are the keys and necessities to success. Since it sounds like you don't go out much there may not be a pattern is how/when you leave, but if there is, BREAK THE PATTERN. Change the routine in whatever it is you do when you leave; do it differently and make no fuss about your leaving. Getting other people more involved in your yorkies life/activities will also help with his attachment to you.
Here is a link to a thread I found here about another member's problem with separation anxiety with their yorkie. I hope it helps.
