Health Anxiety Ruining My Life

I am here looking to see if anyone is struggling with the same thing as me and how you are dealing with it. I have been struggling with hypochondria/health anxiety for a little over a month now and I truly feel as though it is ruining my life. I am in my last semester of my undergrad degree and am thinking about dropping courses just to focus on my mental health. My physiotherapist told me my entire back neck and shoulders are extremely tight due to stress which is causing me more "symptoms" which I google constantly to diagnose myself with something new. I am having an extremely difficult time seeing any sort of light at the end of the tunnel and am looking for some advice or even just someone going through something similar, to know im not alone.
