I'll speak to that from my personal experience when I've had to seek counselling.
I'll self-disclose, I suffer from complex PTSD. That's from tremendous child abuse and then a history of violence, and then witnessing violence, seeing my dead sister's body in the media and on the front page of a newspaper, and also going to her funeral.
Finding healing centres and services that are culturally sensitive was nearly impossible in the community I lived in. First, the counsellors had no insight into colonial historical violence, and I kept having to explain what the sixties scoop was. A lot of people still don't know what the sixties scoop is, and that it's just a continuation of the residential school. Finding culturally appropriate services in the mainstream is really hard, and then getting funding.... I'm only funded for 10 sessions a year through Aboriginal Affairs. Ten sessions is barely digging.... It's just scratching the surface of trauma. Thousands of indigenous people out there don't even know, have no insight into what's happened to them, and then you're trying to get them to talk about it in minimal sessions. There's not enough funding for that. I have to keep reapplying for funding so I can heal from my trauma, so can function in the world today.
So, yes, funding's a big problem: more funding, more funding per person, more healing centres that have culturally appropriate counselling, and also the mainstream. The mainstream needs to know more about this too. We have so many indigenous people moving to urban centres that if there are no culturally appropriate counsellors who have any insight into that, how can they help? How can you help somebody if you don't even know what they're talking about, or how it has impacted them, or even how they're implicated in it?
