Postpartum Depression

I know postpartum depression can be very common & Ive dealt with it off and on since giving birth to my son. More recently I literally feel like there's no hope for me at all. I love, love, loveeeeeee taking care of my son and being around him so thank God it this hasn't had an effect on my relationship with him. But I know in order to be the best mommy for him, I've got to deal with my issues. My OB suggested a therapist who specializes in women's health. How has the recovery been for any of you? Have you had to take meds to control your mood? I hate the idea of taking medication but I feel like I'm out of options at this point.
