Why am I the only one who doesn't seem to be too affected by the effect the covid-19 has had on world stock markets?

The resultant panic and sell-off means that the Indian Index is down 25%. Other smaller ones are down 20%. The NASDAQ has declined 25% in the last month. The pendulum has swung from extreme optimism to unjustified pessimism. Countries have shut down borders and funds and trade will be affected. But it doesn't justify current valuations by any means. Not a single share I bought is currently even 90% of its original cost. But this is a time to buy more.
