>>11325213having had complicated grief from my uncle and mother I can say you never truely let go, you just move on that these people are gone forever and you have to keep going, I still miss them and I can see why some pepple choose to believe in religion as it makes it easier by thinking theyll see them again but I dont but i digress
there is no solid outline I can give im afraid every person grieves differently but the goal is to make a new normal life, I suppose my only advice is not supress feelings and not shame yourself for needing more time, I took nearly 7 years but thats a whole other story, of course youre going to feel terrible, a person close is gone forever, you need to let out all those feelings or they, I can personally testify, seep into all parts of your life and next thing you know youre a hobo in another part of the country
Ive heard talking to others can help though Ive never really did that much, I wouldnt say it helped much though in the end its all falls on you
I ramble too much take away is take care of yourself more, so if you cant let go of regret you can at least forgive yourself and to not supress any needs to grieve and please try to stop doing drugs its really self destructive and is likely worseing everything
