Feeling discouraged. Not pumping enough

I pump every 2-3 hours and still only make about 2 oz per session. Babe is eating closer to 3. So I can’t keep up. I drink all my water, eat, I’ve tried lactation cookies and I just ordered lactation gummies and am only on day 2 with no change yet. Is it possible I’m just not meant to pump? I’d love to not switch to formula but honestly it sounds better and better every time I see barely any milk. And my mental health is taking a slow dip. Tips or advice??
