I can only tell from own experience. But when I had similar things I was quite depressed and some more stuff was going on as well. I was flatout mentally drained so every little thing overloaded my brain. I think I was actually physically not at my best either. Sometimes I was like a kid that just needed a nap or a snack. But on some weird major level. I was so tired emotionally that I could snap or cry from just dropping a spoon on the floor. I needed to clear out my environment from stressors so I became less overloaded, I needed more rest and I needed my mind to get less tired as well. Unfortunately the latter included meds, but at least I'm sort of balanced since many years now.

What I'm really saying is that your mind might tell you that something's too much and it needs a break from it. I think maybe identify stressors and getting mental rest is more important than learning how to stop the outlet.

I used to break things and people told me to break something cheap LOL. But in fact I needed to stop the reason for meltdowns, not just redirect the effect.
