Send your love my way! Losing a parent

Hello everyone. This is not pregnancy or period related sorry!

My dad passed away 2 days ago and I’m just looking for any tips through the grieving period and tips how to cope. It was really sudden he was only 48 and I’m 21. This has been a really rough two days i often find myself feeling guilty for simple things like enjoying a tv episode to “take my mind off things” then i end up balling my eyes out because i feel like i shouldn’t be enjoying things so soon. Please if you have any tips send them my way also well wishes and prayers if you are religious.
