I'm so sory youre going through this. My family is the same way. they all thinnk that I just want attention or somehting. They are also catholic and say that they don't belive in those [psychiatic] disorders, however, my aunt claimed that shes always wanting her way becasue she suffered from PPD 7 years ago. They're crazy. I hope that your mom doesn't fully interfere with your treatment.
Hope you feel better.
