Does anyone else have the sensation that the world as we know it will be gone 5-10 years from now?

I think Jesus returns maybe 2,000 years after He left. I've seen He died in either the year 28 or the year 30. If 28, then we have 10 years before the 7 year tribulation, so that makes your guess of 10 years correct. So if you are a born again Christian, get or stay strong in the Lord and preach as much as you can because we might have 10 years to do it. But don't be lazy. And don't play with sin. You don't know what tomorrow wil bring.
