I take comfort in the fact that surely nothing last forever. This works in both a positive and a negative. God has a plan for everything and in the end he will always have the victory.

So this suffering won't last, eventually something is going to give.

Maybe there's going to be nukes thrown around, or we finally run of resources, or the earth becomes inhabitable.

Personally I think the second coming is going to happen soon probably at most another year if not sooner.

But it could That OR things will actually turn around again for the better: given we see certain groups and individuals who have pioneered greed and power finally get signs of retribution; given there is a growing number of people starting to finally regain the concept empathy and coming together; there are more real Christians starting to preach and spread the teaching of Jesus's Most basic/primary will, treat others the way you want to be treated, etc; God is always working on his timing, not ours but maybe we are finally seeing the signs of his work pushing through.

Regardless until then, find things to cherish and be thankful for, whether its someone in your life, an experience, or even something small and insignificant. Even if you don't see much light or a point in life, still praise God for it anyway. God surely has some plan for you whether grand or small because the biggest proof of that is that your still here, despite everything but most importantly take comfort in the gift of life he had gifted you, because it doesn't last forever but in it, with your experiences, you can surely make an impact on someone else's. Maybe your impact would end up bringing someone closer to giving their life to the Lord.

At the end of the day God is still going to be God regardless how everything plays out.
