how to get over the paralyzing fear of sin?

Since quarantine started last year I have recently learned so much about my faith and sins I didn’t even learn about growing up. It has instilled fear in me that if I “willingly” sin I will suffer the consequences. I have such a negative mindset that if I sin, God won’t bless me in the future, or every consequence is a punishment from God. I have literally lost sleep over this and I feel like its affecting my relationships with those around me. Please if anyone has advice on how to overcome this that is appreciated.
