my milk!!

I am so MAD at myself! For the past month I've been struggling and struggling with breastfeeding. First, I wasn't producing enough and baby was losing weight so doctor told me to supplement which I did. Then I had a health scare and was told not to pump or breastfeed, which I did. Then I wanted to start up again but wasn't making much of anything, so I had to try to get my supply up. Baby still had a hard time latching comfortably and stresses himself out so I resorted to exclusively pumping. I was only making like 1/10 of an oz from each breast, so I started to freak myself out. Why aren't I producing? Am I broken? I tried Mother's Milk tea, Fenugreek pills, and drinking up to 91oz of water a day and saw NO increase from pumping. I was still only making 1oz or less from each breast. I felt so useless but I started to notice something... even though I produced barely anything, my breasts still felt full. At first, I tried pumping longer, tried power pumping, anything. No relief. Today, I hand expressed AFTER pumping and got triple what I get from pumping alone. I was flabbergasted and so angry for beating myself up so much when it was the pump! Hand expressing, I get 1-2oz each boob which feels like a miracle. Now my question for anyone else who had experienced this...how do you handle expressing when an electric pump doesn't do it? Do I have to hand express each time? Any help is welcome, even suggestions for increasing my supply further!
