Can God turn back time or give someone a second chance

Hi. I'm going to be 18 in a few months, and lately I've been feeling really anxious about how much time I feel I've wasted.

Sometimes it genuinely feels like I was 15 yesterday, and now suddenly those years are gone. I keep thinking about all the things I could have done differently if I had the knowledge and maturity I have now.

I've been praying to God every day and asking Him for one more chance — not necessarily to literally travel through time, but to somehow give me another opportunity to make things right and become the person I could have been.

I know this might sound strange, but I've been under a lot of stress and anxiety about this for the past few days.

For those who believe in God, especially from a Hindu perspective: Can God give someone a genuine second chance? Can something that feels like a wasted period of life somehow be redeemed?

I'd really appreciate sincere answers, especially from people who have gone through something similar.
