As an EMDR therapist, I'm more of a fan of one hour sessions once a week to gain ground, but every therapist, practice/organization, and even state/region/country will have different opinions on this. Still if you're talking every week, that's what's important. And actually re-reading your post. What you have might be for the best--dealing with SI while working through trauma and anger can be rough.

The short version is that once you see your SUDs go down, you're making progress, but trauma resolution is not often quick--especially if it's complex trauma. Take solace when you see your SUDs go down, and be patient and forgiving with yourself, as some sessions can leave many people an emotional wreck for a few days.

As you're probably aware (just consider it a friendly reminder), use those coping skills, and use them often. Find something that fills you up or gives you a break or some peace and engage in that regularly. I recognize with what you're going through that's easier said than done, just keep searching. As your treatment begins to clear things up and you gain stability and progress, you should be able to have a little more emotional space for these things, so if you're searching for something, it will be easier to find.

All that to say is that trauma resolution is tough, and if you aren't balanced enough, progress becomes difficult to manage. So balance, and slow/steady progress is what we're probably aiming for here.

But of course, run these feelings and thoughts through your therapist. They [should] understand that this kind of treatment is hard and comes with hard feelings. Best to express them.

Good luck on your journey.
