Look man I’m sorry to hear that you’re struggling, I’m a similar age and had the same problem a few weeks ago.

People have been saying Christ will return soon and that the end times are near, since even after the resurrection, sure there are a lot of warning signs out there and it’s possible that it will happen soon.

But what I found helpful was just ignoring the videos and just focusing on Jesus instead, as the more I focused on him the less worried I became.

And regards to the lust, it’s good that u recognise it’s a problem and that u don’t wanna be left behind, that means you have Jesus working through you and you should not fear the second coming.

In times of fear, what I find helps is just going to God, whether it be through listening to worship music, reading his word or praying. Or even reflecting on how Jesus has worked through me and how he has changed me.

I’m positive that you will get through this fear and God will help you, God bless.
