Hi,
I struggled with depression this past year. Have been seeing a therapist (actually one last winter and a new one recently). We cannot talk about drugs here, but anti-depresants helped me big time. Don't know how that works with breastfeeding if that's what you do with baby, but meds have helped me. Slow my mind and make the bottom less low.
Hugs
PS
Hot baths and walks help too!
