Greetings, @jada1!
I’m sorry to hear you experienced some tough emotions after your cord-cutting ritual. Yes, there are certain types of magick that work with deep and powerful forces within us that tend to leave us feeling exhausted afterwards. Spells like cord-cutting, shadow work, and even deep dive meditations can dig up things that are hard to face.
However, facing your fears and the harder things in life can be necessary steps that lead towards freedom. Hopefully, this cord-cutting spell helped you to find closure for a bad situation you had been feeling stuck in. May this spellwork help you to gain confidence and the strength you need to carry forward to a brighter and more positive future! 
There are some resources here to help recover from emotionally draining spellwork:
- How to help recover after spellwork exhaustion
- Cleansing Coal Shower for Post-Shadow Work
- Guide to Shadow Work
- The Day After Spellwork
I personally have found Self-Love spellwork to be a very soothing and empowering way to heal and strengthen myself after shadow work and other emotional spells.
If you find yourself still struggling to handle the emotions, there is no shame in seeking out trained professionals who can help you calm your inner waters and learn to tame the storm. Know that you also have a supportive coven here to offer love and support 
Sending lots of love and light your way- blessed be!
