Well you can pray and ask forgiveness. Don’t worry about life after death but first try living the one your in 😊
This is one this that is appreciated in Islam, that you should fear about what will happen and hence keep doing good deeds, Your efforts matter the most. If you are intending to go to paradise and doing good deeds, you will definitely be there. It's about making the most of your life, rather than stressing over what will happen next focus on having a good life that will lead you to the ultimate destination.
