How long do you think it takes for someone to

I wouldn’t say you ever really get over the loss of any loved one. Eventually you get past certain stages of the grieving process, but you will likely mourn them for the rest of your life.
It still hurts just as bad, it just slowly hurts less and less often.

I lost my father when I was 17, I’m 32 now, and I don’t think I’ll ever truly be “over it”, I still think about him everyday, even more so now that I’m a father myself. But I grew past the irrationality and despair of it. Accepting someone isn’t coming back takes some time, it is different for everyone.

I would say it took me just under 2 years to accept the first wave of shock, anger, denial, of the loss. Years later I was able to overcome the unresolved trauma, come to terms with how I handled the grieving, and forgive myself for suppressing it all.

Again, different for everyone, and I think most people experience a second wave a little further down the line.

I don't think one ever gets over the death of a parent or another close loved one. It becomes less and less painful over the years but it stays with you. I've only lost one relative so far in my life that I was close to and that was one of my grandmothers. That was now 15 years ago but it still hurts from time to time. I cant even imagine going through losing a parent but it's something we all have to deal with unfortunately.

On average... it takes a person 3 - 4 years to overcome a major "life issue" once they feel safe from further harm by the whatever was causing the trauma.

In most cases the death of someone does not produce further harm after the death; but it can if that person was a critical caretaker for a person that was not adequately replaced by another person.

Thus, in the vast majority of cases for the death of a parent: 3-4 years is quite normal.

I dont think you ever do honestly. I think after a few months or so you're probably able to move on and accept it. Idk for sure because mine are still alive but thats how it was for my mom when her dad died. Still to this day when we talk about him we get sad.

It depends on the person. You should read the 5 stages of grief.
