For the past few months i have been experiencing frequent mood changes, i get angry too easily, try to act so that no one knows that i am sad but cry to bed silently. i usually cry aloud when no one is there. i become aggressive very often. i sometimes feel like committing suicide or sometimes i feel like killing someone or torturing myself. but i cant let these out. i often feel like i am falling from a very deep cliff. i do not get sleep and always think of taking substitutes like sleeping pills or drugs to fall asleep. i just want to run away from everything. i feel suffocated. i feel i am going made. i know i have changed a lot but just cant help myself to revert back.
