HA HA HA, it's so good to hear of someone in TOTAL anguish as I have been

Just joking of course !
What a cute little guy, no wonder you want it home with you so bad. But be assured,
WE all know your misery, but...
The longer you leave it (to about 12 weeks) is much better for it in the long run. Those extra weeks create much better social skills, and there is reasonable evidence being in the presence of it's Mom and Siblings for that longer period, enhances it's health over it's lifespan.
Try to be patient, it'll be worth it !
