Has anyone successfully gotten short-term disability leave for IVF or IVF-related anxiety?

Has anyone successfully gotten short-term disability leave for IVF or for anxiety related to IVF? My firm confirmed with MetLife that they don’t cover STD for fertility treatments. I could get it for anxiety but the paperwork has to be filled out by a therapist who can establish that they’ve been seeing me for anxiety for a long period.

My therapist is through my employer. She’s an independent contractor placed at my firm by a third party agency. She diagnosed me with anxiety 3 years ago and is the one who recommended I take medical leave. She just told me that her placement contract restricts her from making a clinical diagnosis so I’ll need to get the form signed by a fertility Dr. She said she could write a note in support and include the symptoms she sees me for but it will have a disclaimer that it’s not a clinical diagnosis. I don’t see any other therapist for anxiety so I’m not sure what to do. Is there a way my IVF Dr could complete the paperwork without disclosing it’s for fertility treatment?
