How come some people don't let you mourn over death of loved one?

Everyone has been telling me I need to move forward and once a person is dead they're dead.
I mom unexpectedly passed away and I'm devastated. I had to go back to work after I took a week off because I'm needed and they didn't let me take another week off when I wanted to. My moms memorial is next Saturday. I don't wanna do ANYTHING anymore. People have been inviting me to places but I've declined. My aunt askes if I wanted to go to the casino but I declined that too. She told me, "Look I know you're sadden about the loss of your mother. We all are but she wouldn't want you to be all sad and depressed and miss out on life. A evening/night out at the casino can cheer you up. Come on. Get dressed and lets go. I'm not taking no for an answer. My cousins were working that day and my male cousin was him and all the guys were there. Why didn't she ask him if he wanted to go? She's always asking ME not them. She prefers me over her other nieces. Anyways why can't people understand that I need to mourn some more? My dad said it's heartbreaking but we still gotta move forward and laying around sobbing won't do any good.

My family is insensitive.

I'm so sorry for your loss.
It is true that you need to move forward but if its only just happened then yeah they are on you a bit too much. Work is usually bad, they normally demand you come back to work after 3 days here which isn't long enough for most people but your friends and family should let you grieve for whatever time you need but make sure you take care of yourself.
You mother wants you to live a full and happy life as we all loose our loved ones and carry on as your mother herself would have done also when she experienced loss.
Youll be able to feel your mother still loving you and it should bring you some comfort... They take their love with them ❤️
