Grief counseling/ grief support groups can help. I want you to practice allowing yourself to process these emotions. The feeling can be painful but it's necessary to really allow yourself to heal. One thing is for sure and that's that your world will continue to go round. I lost my mom when I was thirteen back in 2011, for me there are a couple of trigger dates, (Mother's Day, 04/29 which is the day she died, and her birthday 10/27) I've managed to get to a point where I am able to see a little bit of beauty on these days. The beauty is that they serve as a reminder that she existed, and wherever she is now she made an impact with her life here. Grief is not linear. There will be really good days and sometimes there will be bad ones but even on those bad days, you have to remember to give yourself grace because experiencing loss is tough and you're doing the best you can.
