Switching to formula and giving up on breastfeeding

I'm seriously sitting here at work dreading going to pump. My supply is getting low from what I can tell (lo was eating every hour over the weekend) and I'm so tired bc he keeps waking up at night to eat. I'm just so tired I cant bring myself to get all the pump shit set up. I was so dedicated to ebf but I'm struggling to stay motivated. Additionally my lo has a bad milk allergy to the point that any milk in my system mikes him vomit for days, keeping very little down and lose weight. I'm just so tired of fighting it. Help!
