Will do. There's nothing like these unsupportive, devaluing responses to one's pain and experiences that can make one feel so doubtful of oneself. My mom pushes the "oh, you just make this up to get attention" line. It's the general dismissal she uses against anyone who goes through soemthing that makes her un omfortable.
My sympathy and my regards to your partner. It is hard to not be believed by the ones we love.
