Is anyone else triple feeding?

Feeling discouraged today. Been trying to implement triple feeding because my milk supply is low (long story, but it dried up a few days after giving birth), so I’m BFing, pumping, and formula feeding AND on top of that, my 3 week old doesn’t seem to want to sleep. Doing all three of these all day is getting to me. I’m exhausted and wondering if my efforts will pay off. I’m on day 10 of the relactation/supply increase efforts and progress is so slow. I get so stressed because I can’t always pump in the every 2-3 hour time frame because baby won’t settle and everything takes so long. Tell me there is hope!
