Breakup

i met this boy and he meant so much to me. we had just reached three months and i thought everything was fine. five days later he broke up with me and told me it was because we got into tiny arguments and it was an emotional rollercoaster for him. i thought i was helping him get better (he has depression from his parents) but he said i made it worse. he told me that he’s been hiding his feelings for a month and he didn’t see the same future i saw. kinda funny because he started talking about living together after high school but whatever. i feel like ive fallen into a state of depression. he was the only person in my life that didn’t make me want to end it all. he made me feel like i truly had control of my life. i have been crying for hours on end. please help.
