stuck

Hi everyone

I was diagnosed with bipolar disorder when i was 15 and was off and on medication until i turned 18. i am now 21 feeling hopeless because my boyfriend broke up with me over a misunderstanding. i feel like the world is crashing down on me and it’s hard to do anything. i have no one to talk to, he was who i talked to on a day to day basis for months. he won’t hear me out, says he needs time to talk, but i feel like im losing my mind. he was my person, and i just don’t know what to do and have gotten little to no clarity or advice from him or others.
