Depression, maybe

Patient: My boyfriend passed away recently in an accident, its been 3 months but it still feels like it happened yesterday. I was fine after that but since last week i feel like im in depression, i don’t go to college much, i eat too much or too less, feel like sleeping all day and then i cant sleep at night, every night i get dreams of him drowning in that water and i wake up in a state of shock..! I don’t go out much and its getting difficult to complete a day without being noticed..can u help me?

Symptoms: Too much sleep but cant sleep at night
