Allah Almighty has already given the best answer for this question:

{Say, “O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah . Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.”

And return [in repentance] to your Lord and submit to Him before the punishment comes upon you; then you will not be helped.

And follow the best of what was revealed to you from your Lord before the punishment comes upon you suddenly while you do not perceive,} (Az-Zumar 39:53-55)

Of course there is a chance for you to get back to Allah. Allah is the most kind and the most Merciful. He is ready to forgive your sins and even to replace them with good deeds if you sincerely repent, turn over a new leaf and amend your ways:

{Except for those who repent, believe and do righteous work. For them Allah will replace their evil deeds with good. And ever is Allah Forgiving and Merciful.} (Al-Furqan 25: 70)

So, please seize this opportunity and rush back to Allah. We are in a very special season of blessings and goodness. So be determined to make the best use of the month of Ramadan.
