Hi there,
That is such a brave step to open up about your concerns. Also, what you are expressing here needs to be evaluated in terms of what is the reason behind your overthinking. Yes, i agree how we over-analyse slightest of the things and predict negative results, while a certain level of anxiety is important for us to perform well in our tasks, it's lethal when it starts impairing our lives in different domains. What you are experiencing as an unrest in your stomach is a physical symptom of anxiety- a feeling of stomach churning, increased heart-rate, sweaty palms and feet and dizziness are some of the many symptoms of anxiety.
