I have a constat fear of crime. i always feel scared that i will be the victim of one and eventually die. i am very scared of death. i tend to overthink everything. and when i start overthinking my heart starts beating very fast and i have shortness of air. i was a brilliant student but i am unable to study at all. i cant sleep due to all of this and i want peace. my parents think i am overreacting. i dont know what to do.
