I am so sorry to hear that you are having problems....and picking which one to give away just isn't an option
especially when you are so attached!!! Have you tried putting the two of them in a small area ex: laundry room, kitchen, bathroom etc...so they are not all over the place?? Also you could put one in a kennel while playing with the other and vice versa? I am not really sure...I hope everything gets better!!! Good luck, keep us posted!!
