hi i am 21 years old and since i was around 7 years old i recall feeling depressed and extremly confused and sad but i was until i was 17 almost 18 years old that i went to a phsycologist and he give meds for depression i take then and from a while they help not a lot but they make little changes they stop my anxiety and only that ,my depression is still there i feel the same with meds or withouth meds the only difference is without meds i experience this states of hapinnes and euphoria where i fell i can do anything and i love people and the world is beatiful and great and i find myself laughing a lot and being funny and then after a couple of days i feel horrible thinking life is a punishment and thinking about killing myself ,feeling a lot of pain to a point where i feel in agony and then happiness again,i've also noticed this episodes where i feel euphoric and sad and the same time .i stop taking the meds around 4 months and i dont go to therapy anymore .i wonder if this sound like bipolar disorder?
