Lost my best friend and traumatised about the way she looked

My best friend died last week on monday november 25. She jumped off a building (dont know what kind of injuries she had) and died a couple hours later at the hospital. Today was the last greeting before the funeral where everybody got to say goodbye to her body.

What i saw kinda traumatised me.. i almost didnt recognize her (and i was not the only one).

She looked like a wax, stiff doll. It seemed like her skin was fake. You could see that they had to re do a little piece of her nose. When she was alive her hair was always straight and flat, now it was fluffy.

The thing that bothers me the me the most is the fact that she looked VERY uncomfortable, forced and restless.. also her mouth was still opened a little bit so she was looking sad. Ive seen a couple of dead bodys already and you could always say they looked peacefully asleep, but that wasnt the case with her.

Why could this be ? What did possibly happen during the embalming? Why did she look so unreal?

I still cant believe she is physically gone, not even after seeing her laying there. The whole time i stood there and when i touched her my brain was convincing me she was breathing. How do i get over this?
