Weaning blues

Need some support!! My 1 year old is breastfed only (no other milks and no bottles). During the day she nurses 3 times (when she awakes , when I come back from work at 2 pm and 6 pm before bedtime). During the night she was confort nursing as much as 6 times per night which meant I didn't get any sleep. So 3 nights ago, after I got to a dangerous sleep deprivation state I decided I wasn't night feeding anymore. Today she slept at 07:40 pm and it is 02:30 am and hasn't awoke yet. I did because my boobs felt sore so I had to pump and dump for my own comfort. And now I am feeling sad I no longer BF at nights, reaaalllly worried my milk production will dwindle and I won't produce for those three remaining day feeds and that she might wean herself to just 2 feeds per day... I miss my baby baby!!!! Anybody can relate? Am I right in doing so? She's 01 y and 20 days old. Is it too early to BF only 2-3 times per day????
