Will pressing a key on the keyboard continuously for a very long time to play a game like Roblox affect/hurt myselfdamage my nervous system?

I'm quite a paranoid person recently, more specifically health paranoia. I have been easily getting non-stop worried that certain actions (including turning head fast, scratching, rubbing, hit something, etc.) will affect/hurt myself/harm or cause permanent damage to my nervous system/brain and make me feel not so good/differently forever for the rest of my life. I haven't play Roblox for many months. So, now I think since I had become so paranoid, I can't even play games like Roblox anymore for the rest of my life, which is so disappointing. I think if I play it, my brain will immediately be paranoid that pressing the WASD keys to move the character in Roblox/Minecraft continuously is hurting myself or damaging my finger and changes the muscle/permanently stuck or something like that. What are your advices? I'm not sure if any of you can successfully convince my brain that it's fine though since it's very paranoid. I even tried to tell myself, I played it last time and millions of people play it and they are fine, but my brain won't listen.
