I've been suffering from depression and anxiety for 5 months now and am currently on antidepressants, but i was told today that i would be being referred to see a neurologist to have a CT scan to rule out anything being wrong with me in my head such as MS, parkinsons etc.

Is this is a normal thing to do as i am really worried now that i may have something bad wrong with me or something.

I hope they don't find anything wrong with me in that way.
