I do not have a teacher but I have a monk who agreed to help me through my Buddhist path. I’ve told him I practice impermanence and metta, I told him a little bit how I practice impermanence and he had nothing to say but I think he didn’t understand me because he said “when you sit on impermanence” but I basically don’t sit on impermanence I do it everyday in this type of way “the rain is falling but it is impermanent it won’t last forever, I am feeling anger this is impermanent, I feel happy this impermanent” and I go like that through the day. I do sit for metta though. I wanted to practice on death next because of my ptsd and bipolar the monk told me I can’t do samatha and vipassana, it brings back memories that aren’t healed yet.
Death is an impermanence meditation. It’s really helpful for sloth and torpor and restlessness and worry.
I use an anapanasati formulation, breathing in I know this could be my last breath (arouses the mind), breathing out I let go (calms restlessness and worry).
I learned that from Bhikkhu Analayo’s guided meditations. All of the series are good, but the meditation I’m referring to is here.

Three is contemplation of death. Five uses the death contemplation to pacifiy some of the hindrances.
If you look through his other offerings there is also Brahmavahara meditations and an Annapanasati formulation that contemplates impermanence of the aggregates.
Thank you so much I’ll look into the guided meditation.
