I think you need to just cut them off during this move your making, If they are going to just add even MORE stress and shyt. Stop speaking about it on all levels to them.

I think if you make this move on your own without including them and their ridiculous drama adding to the mess, your going to feel stronger.

Its ok to not like your kids, You love them but you don't have to "like" them.. I have felt this way about my daughter at times and her and I are best friends.

Focusing on packing for 30 mins then take a break then go back for another 30 mins, Mentally it just allows you too know that after 30 mins you can take a break.

Try and hang in there
