Regrets pile up. Whether you regret switching careers, staying in touch with someone or just little regrets. They pile up in this bucket of emotions and soon they over flow and you break down because you don't know what to do anymore. But theres always time to do things you regret if you regret not joining a club try joining something. Try not to focus on the regrets because you are who you are. You can do what you want. Even if you dont think it was the right decision it probably was at that moment, trust yourself and make the decision that you think is right.
