Well I found a midday nap helps with the tiredness. Only for about 5 to 20 minutes. Trust me. Otherwise I don't really have a way to deal with them. I have been conditioned out of them by some not-nice parents

I am not sure how to decrease the amount but I find watching deep look animal/bug videos on YouTube completely calms me down and they are super short which is nice!

Breathing like square breathing is one thing that helps me

Figure out what triggers them and try to work around! I keep ear plugs in my pocket at all times, for example. I find that knowing yourself and what distresses you the most, then getting ahead of it, is the best way to ensure you have a good day without too much issue.

When I start getting stressed I try to take a stim break. Maybe I’ll put music on and spin or something like that

Depends how much things messing with your sensory intake example if I'm in picture day at school to many people in one room Plus the flash of the camera tiggers you I causes me too cry and break down

find your biggest trigger and do what you can to avoid it or lessen its impact. for example, I get overwhelmed super fast if there's a lot of noise, so I ask other people in my house to be a little quieter and if I'm going somewhere where I know I won't have control over the volume level, I'll bring active noise cancelling (ANC) headphones to dampen the impact on my ears. I also ask the people in my life to give me plenty of personal space because if I feel cramped or crowded I WILL start screaming

If you can pinpoint your Rumbles (signs of an oncoming meltdown) and cope and stim and whatnot it might help. You could try journaling about things or you could try an app (i recommend tochi diary) so you can pinpoint what tasks, interactions, etc. Cause you to feel worse. Then you can work from there on how to make it not so dreadful. Hope ur well!
