I wish I could help. When I got my shorkie, Eva, I DESPERATELY wanted her to be pad trained instead of outdoors, since it was winter & bad weather, etc. She never once, no matter what I did.. understood going on the pad.. She would just pee/poop in my room if I did not take her outside. Still to this day she does not understand the whole pad thing- so we gave up pads/indoor methods all together. She is trained outdoors now, but it took about a month for her to really get the hang of it. She is almost 1 now and she does still have accidents, but she understands going outside is the right thing to do & I am happy with her progress
Overall, just hang in there & keep trying.. it will get better I promise. The first couple weeks are so hard, but once you get past it.. it only gets better with time!
