sounds generic but i was the same way when the dog i had for near 13 years died from being euthanized, made all the more harder because he was dead by the time i woke up, shit gets better and you just gotta realize that what youre going through now is just a small portion of your life, near any bad thing you go through at any given time will just be forgotten or gotten over with time, simple as that, and once i realized that it made most hard things just that little bit easier- yeah life sucks utter ass at times but sometimes thats just what life tosses at you and you gotta get through that before you can get to the good shit that life will give you
tl;dr, life fucking sucks sometimes but u gotta deal with the shit to get to the good sometimes, all the bad shit in life is just a small portion of your life and youll be over it in no time, always think of the long term
