How bad is the child neglect/abuse?

I'm asking because I was severely neglected and abused as a child (as well as escaping into imagination to cope). I really would like to see this, because I love creative, mindbender films, but I'm worried that it may be too close to home for me and might set off my PTSD (post-traumatic stress disorder).

[Warning for descriptions of child abuse ahead.]

My parents weren't the same kind of junkies; my mother didn't do drugs at all, but my father was an explosively violent alcoholic who huffed various chemicals and who knows what else. I often had nothing to eat, lived in filth, was refused medical attention (even with severe blood loss and so on), had to take care of my younger siblings even though I was a child too, was constantly bruised and ravaged by insects, beaten near daily with planks of wood, surrounded by crazed hicks, forbidden from most forms of entertainment (but I snuck what I could; I loved movies so much!), not allowed to go to school (until I was 12 and I guess the city forced them/someone turned them in for it), etc.

There was also religious/psychological abuse; for instance, being exorcised of "demons" for having an asthma attack, since I was supposedly healed of that, so I was apparently either faking or possessed.

There was some sexual abuse too...

So, yeah. Do you think it's too similar? Does it focus on reality much?

Sorry to bring people down by talking about my childhood. If it makes you feel any better, I disowned them and skipped the country. I'm still pretty messed up though. :/

I'm fine with most gore (bruising's a bit much sometimes though). I love horror movies. I'm just not so good with especially cruel things; especially if they are directed toward people who can barely defend themselves (children, animals, abused women, etc). I'm fine with sexuality; just not the abusive kind (BDSM doesn't count; I mean non-consensual stuff - child molestation and so on).

I've watched some pretty extreme stuff and not been that bothered by it. For instance: A Serbian Film (one thing near the end did bother me), Takashi Miike films, Guinea Pig films, Aftermath, Antichrist, etc. So I'm not exactly a fragile flower; I just have my limits.

Thanks in advance for any insight.
