Paul,
Loudspeaker DIY can be very all-consuming. It is normal to feel the way you do. The important thing is the journey should be just as enjoyable as the destination. If you're not having fun because you are tired, stressed or worried about other things, they will happily wait until you are ready to enjoy building them again.
The down-side is they do take up a fair bit of room and so you may have some pressure to get them over and done with. I hope this is not something you have to grapple with as well, because that will undermine your efforts and quality.
If it is any consolation, I don't think Gareth has finished his own pair yet either. Good things take time. I assure you they will be worth the effort. In the meantime, take some time off for yourself and enjoy the Christmas festivities.
James
