You can heal broken bones.
You can't heal broken mind.

Both are dreadful, but I feel like emotional takes significantly longer to recover from if you do at all. And even with a nearly full recover, that shit tends to resurface every now and again in some way or another.

Sorta hard to chose because they can both be horrific, but probably some of the worst abuse is when they go hand-in-hand eg. in domestic violence, the abused partner often feel they cannot leave (even though they've been physically abused) due to the emotional abuse and manipulation of the abuser.

So I'd say emotional abuse often facilitates or exacerbates physical abuse

The pain is real

I say both, but still this scar remains forever

Depends.
Both depend on quantity. If the amount of one is greater than the other, it will be that one. So, both are equally painful, tbh.

Unhappily I relate.
