What should I do?

Okay okay, quick context i'm planning to do somatic therapy, or EMDR or any sort of embodied processing eventually.

However, i'm also still in the traumatic environment that got me to this point.

Recently, family has had a bit of a...interesting melting point thanks to my brother so hopefully it's taking a direction to the better but it'll take awhile. (And i still have doubts considering the amount of times it gets better then worse then better and that screwed up my trust a little.)

I wanna process this. I wanna move on. I don't want to have the fear in my body halting me, or the unnecessary pains.

But I'm wondering if it's better for me to try this when i'm out of this house first.

Originally i planned to just go on with interpersonal building with my psychologist and other things, and then process it when i'm out but if it might get better, should I just go for it?

I'm just scared since i've heard it can be rough? Though i guess that depends, and well, I don't mind going through it, it's more that i don't wanna worsen it.

I got no clue.

Any thoughts?
