depressed ?

im so emotional and i get connected to people so easily that my boyfriend says he feels trapped in the relationship. I'm too afraid to go to the doctor to get diagnosed but i think i have severe depression because i cry at least once a day and it's been a few weeks-a month. i care about people too much and they don't reciprocate and i can't process it without seriously just wanting to die and i don't know what to do about it.
