Postpartum depression: A family hopes their loss will help others

Nima Bhakta enjoyed the beach in Puerto Vallarta, Mexico, celebrating her father's 60th birthday with her extended family on August 16th, 2019.

(CNN)Nima Bhakta was that college friend who everyone knew would be a great mother.

We met in 2006, and I could see that she was always at ease when she interacted with children.
Kind and confident, she was also the friend who talked about how excited she was to have children of her own.
    That's why it was such a devastating loss to her family, friends and to me, when she lost her battle with postpartum depression and died by suicide on July 24. Suicide is one of the leading causes of death in women with postpartum depression.
      Nima Bhakta (L) and author Sneha Kohli Mathur (R) became roommates and friends at the University of California San Diego.
      In a letter to her family before she died, Nima wrote that she tried to tell her loved ones about her struggle with postpartum depression but she hadn't been able to find the words to explain the depth of her suffering. She wrote that she had a loving and supportive husband and that no one was at fault for her pain.
      It started, she wrote, after her son was born in 2019. She felt completely changed as an individual, wife, sister, daughter and aunt, and she didn't understand how she couldn't even attempt cooking or other things that she once enjoyed.
      Her constant worry about the future and self-blame for any difficulties with her son overwhelmed her. She got to the point that she believed that she was a complete failure as a mother and was scared that she would cause him harm in the future. Throughout her letter was a sense of shame for needing help taking care of her son, and guilt that she wasn't feeling better despite having an incredibly supportive husband, Deven Bhakta, and her sisters and family.
        In her text messages to me she expressed she was experiencing postpartum depression. "Everything I do for Keshav just seems like a task for me, it's been hard to have that bond between me and him. Really didn't expect all this since I love kids but with Keshav I've been struggling. I haven't been out of the house either unless it's for a doctor appointment, it's pretty bad. Deven's been such a big help it's ridiculous."
        She couldn't see what a wonderful mother she was to her beautiful baby boy. I saw her as a devoted mother diligently attending to all of his daily needs. I could see she loved him so much.
