Ah, things are pretty tough right now then.
So, emergency hits to the system (DBT offers some good strategies) are things like jumping under a cold shower (do it fully clothed if that’s what your head needs - the shock to the system is what makes this so damn effective), or keeping a couple of oranges in the freezer that you can pull out and hold in your hands. They don’t offer the visual impact of cutting, but the physiological impact is similar, and can be very effective if you couple it with your thought-stopping strategies (see DBT or ACT for thought-stopping or thought diffusion techniques).
Definitely it sounds like upping the self care is in order. Things are particularly difficult right now - life has thrown some major curve balls at you. You probably don’t feel like doing nice things for yourself, things that just make you feel calm or safe. But those activities built into your daily routine can be incredibly powerful, because they support recovery on a number of levels.
Cutting gives a rush. But it’s deceptive, because once the rush is passed? You will already have experience with what happens after for you - usually some pretty nasty (and spiralling) self talk, shame, and ultimately chasing the temporary ‘relief’ again and again (and the thing it’s meant to relieve still as big as ever, if not more so). You probably didn’t experience that in your dream, but there’ll be a reason that you stopped using SH as a coping strategy last time. Use that experience, and knowledge of yourself, to your advantage.
