Maybe.

But there's always someone who will have it worst.

I think I do; cannot truly say that I know, whilst I can truly say I've witnessed suffering at first hand as SOME might define the word. Does that mean I 'know' what it feels like? I've had my share of heartaches (as many have) I think I suffered during those bad times; I think I qualify.

since birth...physical and mental

Yes.😞

Its a perspective in some ways and theres also mental and physical suffering I've experienced mental suffering all my life

No, never even heard of it.

Yes .... I'm no stranger to suffering.

Oh yeah.

A type of suffering, yes.
