Is it normal not to feel sad for fathers death?

It takes me a while to process shitty things or life changing events. It’s normal. Sorry for your loss.

You can't control what you feel.
Grief can be delayed, it can take a while for it to sink in what has happened and meanwhile you can feel as usual because you're in shock and denial.

For me it hits me later. I'm sometimes not sad right away at the funeral.

There's no standard, "correct" way to grieve the loss of someone close. You're probably aware of the Kübler-Ross model of five stages of grieving. That has some validity for many people, but it's not a neat linear progression and it's not like a law of physics where every psychologically healthy person experiences exactly the same depth of emotions for the same length of time.

When someone we know dies, we feel what we feel because of the person we are and our history with the person who has died. However, every culture has deeply-embedded standards of the "right" way to grieve, and people can get upset when they see others not conforming to those cultural rules.

You seem to have a rational view of death, and you say you expected your father to die. That makes me suspect that you came to terms with his departure some time ago and basically did your grieving before his death. This isn't uncommon when people are terminally ill. Often people mainly feel relief when someone who has been slowly dying finally does - and then they feel guilty because they aren't feeling what they think they should feel.

Your mother is clearly feeling this more deeply than you, and that's just as normal as what you're feeling. It's also normal for her to be angry with you for not being more upset. Very often, when someone we care deeply about dies, we feel anger that the world continues turn and people continue to get on with their lives when there's suddenly an enormous hole in our own life. It's not unusual for people to lash out at such times.

As cupcake says, it is possible that you haven't fully internalised what's happened. You need to be aware that the fact that you'll never see or talk to your father again might suddenly hit you when you least expect it, but you shouldn't keep prodding away and trying to feel emotions that just aren't there.

You have the right to deal with this major change in your life in your own way. As for your mother, the best you can do is accept that she's dealing with it in her own way, do your best to be patient with her as she goes through her own process of getting to acceptance and do what you can to help her cope in practical and emotional terms.

yes, that is normal.

It hasn't sunk in yet. Normal

Your maturity has allowed you to accept this and move on with your life while still remembering him. Dont feel bad but also dont deny others their time to grieve and different ways to do so.

my father died when i was 8, im 15 nearly 16 now, i never realy cryied. i never felt realy sad, its probably because i never realy got to know him so i guess its normal

Grief is different for everyone. Some people don't experience any of the stages. And it's actually very common to feel relief when a person dies.
