please, how can i feel better after my breakup?

i just broke up with my boyfriend of 1 year and it feels horrible. i have been hyperventilating, having a hard time breathing, not eating, no energy to do anything, i feel hopeless. i don’t have any friends close to where i live, my friends all live hours away. currently i am living in the apartment we shared, and i am reminded of him everywhere i look. i constantly break down crying and i wish the pain would go quicker. i don’t have any hobbies and i’m also currently unemployed, i don’t have anything to distract myself from how i’m feeling. i don’t know what to do, please give me some advice
