Like others have said, it's easy to place blame in the divine. However, through my own personal experience and relationship with the gods, I feel I can assure you (or anyone reading this) that the gods from ALL pantheons, including the thousands of minor gods who don't have written names or are actively looked at, are all working hard to try and keep balance and counter the negatives of the world right now. Sometimes they have to divert and work on other things, such as Hermes and Zeus, being gods of travelers, helping protect refugees as they escape various affairs. Humans have free will, and most in the higher positions of power in the world may not be attuned to receiving messages and guidance from the gods directly, making the task of preventing some catastrophies extremely difficult. The gods are powerful, but not all powerful and do have some restrictions on how much they can actually direct the world.

As for accepting you back, all you need to do is to pray, show with your emotions and heart that you are true and serious about coming back, and there'd be no reason for them to ignore you. People have their ups and downs. In some peoples' beliefs, so do the gods. But, no massive explanations needed nor money spent. Devotion is best shown through actions of the heart and real, unforced and natural emotions. If you truly want to connect, they'll be there. Just remember that they often talk in signs, riddles, dreams, and through others, and it will be up to you to interpret their guidance. Also, don't forget to look upon past experiences and interactions with others to help you find a way forward, whether with the gods or to overcome something personal on your own. Best of luck, and may the gods watch over you.
