Kick out the negativity!

It's the last day of November! The end of the year is already right around the corner and in one month we'll face another new year. These days I've been thinking a lot (since Im already in my last year). Can I pass my final practical exam and be able to do the clinical rotation in first or second batch? What will I do when I have graduated and become a doctor? Where will I be placed for the internship program? What is actually my interest in this field and where should I continue for further education? I have this kind of insecurity. People said we should just live for this moment and enjoy it. I guess this might be true for person like me who is always overthinking most of the time. I hope I can reduce the negativity out of my life and be a more positive person in the future. Fighting!!!
