How can I check my hormones in the Cerebroespinal fluid?

Some of my hormones are in range for example cortisol but I have many many symptoms of pseudo cushing’s in order to get medical validation (no doctor believes there’s something wrong with me they just say I’m “depressed” and lazy… ugh) is there a way to get the hormones in my cerebrospinal fluid tested? I think hormonal imbalances we have don’t really reflect on blood since this issue is neuroendocrine
