Dear Sam, I received your letter and I’m really worried about you. I understand your feelings and have been in a similar situation myself. This is not an easy period in your life, but difficult times pass and everything will get better! I think you need to take a break, relax, sort yourself out. Remember what you are interested in, what you really like to do, or what comes easiest to you. I remember that you were really good at biology and chemistry was easy for you too. Just challenge yourself to be the best in a particular field. Don’t forget, the road to success is never easy. Set yourself the task of surpassing any barriers that stand in your way. You will be able to get a good education and become a good specialist. Personal achievements and a sense of satisfaction from the results will give you a great feeling. I believe in you! Keep in touch!
Best wishes,
