I have been meditating for a while, specially Vipassana and some metta. Some times I feel everything more intense than I'm used to, sometimes I feel so good, but other times I feel the weight of the vices of my untrained mind and I hurt myself and other with words, actions and thoughts, I have tried to stop this behavior with metta, but some times my emotions are so overwhelming that I can't just stop myself. What should I do?
