I have been experiencing sadness and loneliness since months but always got myself distracted doing some housework or college work. But since a few days, the distractions are not helping and I'm not feeling to talk to anyone and I'm being constantly sleepy and a mild headache. I feel to be alone and not developing interest in doing daily activities, though I'm doing it forcefully. My appetite is normal as before. Also, I'm a PCOS patient, so have been a lot of medications since last five years.
