Have been facing a lot of stress due to academics, which also makes my mother yell and insult me due to me constantly failing in exams, i am not able to sleep like how I used to, i constantly wake up every few hours, need to take deep breaths atleast 2-3 times a day, i catch myself crying at times without any reason, i see my leg shaking every now and then, i feel cold even if the fan is not on. Never been in a good mood since so long I constantly fake being in one when i am around people. Do i need help ?
