I’m sorry for your loss. Allow yourself to be sad, it’s completely okay. Anyone would be sad and depressed in this situation. Take your time to mourn and then when it feels right, get back up. Don’t put a time on healing, let it sting, but try to do things you enjoy and don’t put off your responsibilities. I bet your dad loved and appreciated you and would want to see you striving and being as happy as possible everyday. Remember him and continue his legacy. You got this OP, I hope this helps!
