Sometimes I say things too quickly, and in this case, it causes me more grief than relief.
However, the moral of the story is that if you can admit your faults (mistakes), try your hardest to attain your goals, and be honest with yourself, you should regret nothing.
Because everything we do in life is all to ensure that we don't regret. I cant help but beat myself up about this, but it isn't my fault it didn't work out. Making the decision I did as quickly a I did it brought out true colours. They would have come out eventually.
