Hi, It'sover900. First, welcome to RR!
why would they want to be here during then?
Second, I don't like to assume this but it seems like a "holier-than-thou" kind of thing; almost as if they feel like they have to go through it or else they aren't worthy or something. The truth is, there's nothing wrong with wanting to avoid the Tribulation (besides, the Bible tells us we will). The Tribulation is going to be the absolute worst seven years this Earth has ever seen. It will make 9/11, the Holocaust, and World War I and II (combined) look like a day at the beach by comparison. Nobody wants to be here when those seven years happen.
The Tribulation, according to gotquestions.org, is: "...a future seven-year period of time when God will finish His discipline of Israel and finalize His judgment of the unbelieving world." We are not part of that because we are not unbelieving.
Now faith is the substance of things hoped for, the evidence of things not seen. Hebrews 11:1
In the event of darkness, depression, sadness, or loneliness, your Bible can be used as a flotation device.
