Hi, If this issues persists for long and there is no particular trigger( incident) that you can identify, it will be best if you consult a professional. A psychiatrist usually prescribes medication if there are several symptoms of anxiety or depression or any other psychological condition. A therapist/psychologist can also assist in the diagnosis as well provide therapy to address the underlying issue for the problem.
