#I told myself: come on, that's the most trivial thing they could say to weaken a weak person.

There are many obstacles on your way. It can be a barrier from yourself or a barrier from people around you. If you let that affect you so much, you will always be tired and more likely to let your attitude down and disappointed on yourself.
You are not sure about what you do, but you can be more confident about yourself.
Right now I am in need of confidence to face to the people around.
Do you know that right now they are better than you, they know more than you but you are still learning.
You have not finished yet.
Do not let your inferiority take over your person and turn what you longed to become bad. Remember that these days are exactly what you desire every night during the year.
Remember that everyone wants to show that they are better than you, they want to win you and make you feel ashamed of yourself.
So do not let the things they say hurt you. Use it as an incentive to move forward. Overcome it and one day, when thinking back, what they said was the most trivial thing they could say to weaken a weak person.
