The Rapture

I am 15 and I’m not gonna lie I am very nervous for September 23-24. I’ve been a Lukewarm Christian for about 2 years now. And I wanna try and do better but I am so controlled by lust that it doesn’t even seem possible for me I personally don’t think I can change the person I am within 3 weeks. When I heard the rumors of Jesus return on September 23-24 I got really scared so I tried really hard yesterday to not go on any 18+ sites. And I did but it scared me so much I started crying I realized how crappy of a person I am. I went to my room and just cried saying stuff like “god I’m so sorry” and to be honest I’ve never really cried about something like this before. If anyone has advice for the whole September situation that would be appreciated.
