Hey @leila, maybe just back off things for a bit. You might be jumping ahead and worrying about things you imagine to be stressful such as self immolation and things like that. I have seen this personally before, where someone was freaking themselves out over the somewhat intimidating subject matter. But the actualism method, especially initially, is just a simple thing about feeling good.
Can you notice how you are kind of creating a drama out of it? Getting yourself all worked up? See if you can notice those feelings, see the harm they are doing (you feel stressed/anxious) and allow yourself to get back to feeling good.
Alternatively, if that doesn’t work, just take a break from thinking about actualism for a bit. Once you feel good again, you can look at this and work out what was triggering you.
