Lost my dad... my life

I just lost my dad April 24th to heart issues brought on by Covid 19. My dad was literally my world. I worked alongside him everyday. Him and my mom lived with me so I could take care of them. But until he suddenly died he was in good health... for 79 years old. I pastor the church that he lived for... I mean nobody is perfect but my dad loved God and his family. Now it’s me and mom and we are lost. Destroyed.... we literally don’t know how to go on. I know my dad is in a better place but it doesn’t ease my pain. We owned a business together and I dread having to go back to work without him so bad. I literally feel like I’m dying and even with my faith I am in misery. Thanks for any support or suggestions. God bless ...... Seth
