I mean bro it's gonna hurt, the more time that was spent on that thing from which u got heartbreak from, the more time will be needed to recover. Life will be slow tbh and painful, u just grieve and talk with people abt it if possible , also u will start to remember happy memories Abt her ( I am assuming heartbreak means a girl broke ur heart) but try to balance that out with all the sad experiences with the person as well. This is a general thing that often when we start liking a person and go through heartbreak we think we loved the person but in many cases they actually didn't, we create a completely different than the reality version of the person in our heads according to ourselves and like that imaginary version and not actually the real one, try focusing on this. Also speaking from personal experiences yeah it's gonna be really painful, my first time I didn't have an appetite for 2 months and just watched series and anime and movies
