Losing weight while BF

15 months breastfeeding/postpartum.. how the FUUUUUH do you lose weight 😭😭 I’m 155 and I want to be down to 130…. I am constantly frkn hungry and when I don’t eat enough I get shaky and my blood sugar plummets. I’m at a loss. I had a csection . Been walking 2-4 miles daily/ every other day. I bleed with physical activity(such as walking like I have been) if I do more vigorous activity I bleed like a period. I’m annoyed abs fat and moody!!!!!! Being this uncomfortable in my tight ass clothes makes me want to cry. Help.
