Terrified About Workup

I am being worked up for symptoms concerning for Multiple Sclerosis and I am terrified. I am a physician but not in this field so I know just enough to be dangerous. I’ve worked countless models to no avail; I know it’s not working because I am not able to believe my alternative thoughts (ie. It’s probably not MS, even if it is I will be okay). Thank you in advance… I feel like I am drowning and it’s been so long since I’ve felt that way thanks to SCS.
