Yes, you can return to the Gods and our path. Meditate, practice Yoga, perform God Rituals, work magick, and study. Our Gods are understanding; they know that we sometimes face overwhelming situations that can lead to regrettable actions.
What matters the most is acknowledging what has happened, let bygones be bygones, and move forward. Learn from your mistakes and work toward becoming a better version of yourself. This is the path we all strive for - to become like the Gods.
Since you have bipolar tendencies, it's important to be mindful not to overextend yourself with meditation, God Rituals, and magick. Know your limits; understand how much you can comfortably handle, and when it's best to step back a bit. This is to help protect your well-being and keep you balanced on the path. This is imperative.
Smaller, consistent spiritual programs build greater power over time than intense, overwhelming programs that burn you out quickly and set you back.
Take care!
