New to Nvidia

I'm getting scared now. I bought in a few weeks back at 120. Felt amazing when it rose and now obviously panicking. If I wasn't panicking I wouldn't be human right?

I know no one knows what the stock will do, but just any advice on coping through the drop will help. I don't need this money, can hold for 5 years, but could it just become a nothing company and back towards penny stock levels?
