Vicious circle in Lifebook

For 4 consecutive hours, I wasn’t able to write one word or make a progress in my MA thesis… Mood swings made the matter worse. This is the outcome of choosing a field that I don’t love or I’m not passionate about. I think I deserve this !!! All that pain, lack of sleep and confusion for nothing.
To all the people right there, please fight for your dreams and passions and don’t let others decide the next step you’re going to make in life.
