I am a failure.

I have to leave my baby in 3 weeks and I will b gone for 3 weeks. In my fridge isn't even enough milk to do her 1 week and bo matter what I can't get up at night to pump extra. I tree setting alarms on my phone both me and my husband wouldn't wake up or the alarms never went off or I turned them off in my sleep. I bout an bell type clock with the hammer and two bells on top anoying and loud of course it will work. Sure did 1 night the next my husband gets up and turns it off in my sleep deprived state I go with it and when he gets up 3 hours later I think it's all the same time and yeah time to pimp no fuck my life it's time to feed her and get the day started. I don't know what to do except start supplementing which isn't bad. I just wish I had more self resolve because if I could just get up/ have been getting up we would have more milk in freezer. Anyone with advise on how to pump more or a similar situation and how you resolved it please help I am laying here crying because I don't k ow what all I can do anymore.
