how can I produce more breast milk?

Mazie💕🤷🏼‍♀️
I'm literally so sad that I'm not producing enough milk but I know my baby needs to eat. I'm mainly sad because I love the bond we share when I do feed her, but it's gotten to the point of when I feed her you can tell she's not satisfied.. so my questions are when you stopped breastfeeding were you sad? And how can I produce more milk?
