When you are told that it is completely “normal” to be depressed and suicidal on a daily basis?

I openly talk about how I feel with my partner and I get triggered when I’m told it’s normal.
I feel invalidated, how is it normal ? Is it normal for a 7 years old child to what to die? Is it normal for a 10 years to attempt suicide and self harm? 
I’ve been on the same track for years, I’ve been suicidal and struggling with self harm for years.

I’ve had my diagnosis for as long as I can remember and whenever I discuss it with them, it’s like he tries to normalize it to make me feel better but to me it just gets triggering, like I’m being invalidated and it shows they simply do not understand or know the struggle of BPD.
