am i depressed?

i’m on birth control and lately once and a while i’ll get super emotional and then i think everyone hates me and how i’m worthless and i cry and get myself into these moods where i feel like everyone would be better off if i moved away somewhere where i know nobody and maybe i’ll be happy? it doesn’t help that my friends are really fake but i realize it more when i get like this and i get really upset for a few days where i literally cannot stop crying then i’ll be fine for a week or so and then it’ll happen again
