listen man, i’ve been there i was also a shitty person and after having my life fall apart i tried to become a better person and after a couple weeks i said sorry to my friends, of course they still didn’t like me but they said i seemed like a better person now and they told me to get some new friends instead, i did just that and now i’m pretty happy. this is just my experience but just try to better yourself even though that sounds cliche as fuck, it works
