life rn

this is kinda a bit of a vent but im also asking for advice. 

ive been losing a lot of people lately and its just become so sad? idk if thats the way to put it but its just been very lonely. 
my ex bf has been spreading rumors abt me since september and its just tiring hearing it constantly said. thats the reason im losing friends cuz of the rumours, ppl i thought cared abt me pushed me away because of what he said, which isnt true btws. 

what should i do abt this? ive been trying to make new friends, should i just not care abt what he says? or idk

any1 got advice?
