The chances are you would not survive. Here is why:
Our technology is developed enough to protect us from a lot of the disasters which previously would kill hundreds of millions, so whatever the next catastrophe would be, logically, it must be something at a much larger scale than ever recorded in the current human memory.
If it is a natural disaster like meteor, then, as you have seen the movie 2012, everyone on the planet dies except those who are evacuated in the arks. So regular people like you and me stand no chance.
If it is a biological virus catastrophe, then again the elite will be put in isolation and protected with guns and walls like also illustrated in many movies of that type. The “outsiders” are left to fend for themselves and form murdering gangs. Again the vast majority of population dies and the remains are either mutated, radiated or basically doomed to failure one way or another while the elite continue evolving into an even more powerful civilization.
If it is World War 3 with thousands of nukes launched and hitting all over the planet then we destroy the planet and all die, except, again the elite who will be with supplies living deep in the Earth in already built bunkers and waiting for the grace period while the Earth heals itself and after X years they will re-emerge to the surface.
If it is a financial catastrophe then large commercial companies take over control of the planet and enslave the population to the point where the life of the individual has no value and can be terminated at wish.
If a technologically superior alien race comes along then as in the whole history of the human race the superior civilization always ends up enslaving or committing genocide on the inferior civilization.
I’ll stop here, tired of writing.
1 final point. We were tough and could survive “in the jungle” before and then we got soft. Now if the soft is thrown back into the jungle s/he will be destroyed. It is easy to become soft, but out of 100 only 1 soft could maybe become tough again.
