Of course it doesn't sound awful! You have several small children at home, so I'd place a bet you have had maybe 5 years of reduced sleep, bonkers hormones, being touched all the time by other people seeking comfort, logistical stress, financial stress, changes in priorities, changes to your body, less time with your partner ..... it would be a surprise to me if your libido wasn't affected at all by that!
That said, I think hormones play a big part. I ebf my twins and had absolutely no libido. The thought was exhausting! Then one day I woke up randy as hell (much to DHs surprise!) .... two weeks later my first period in 27 months arrived! I have always noticed an increase in libido around ovulation, but was surprised that the very first ovulation post pregnancy could suddenly wipe out all the other stuff. I was still Breastfeeding the twins at this point (18 months old, feeding maybe 4 times each in 24 hours), so I am sure it was the return of ovulation that changed things, not any change in Breastfeeding habits.
Give yourself time. Meanwhile, talk to your DH and explain that all the massive changes have affected your libido but you still love him and think it will all come back eventually. I hope he is understanding.
