As someone who lived through a coup attempt in my home country and its aftermath I have few things to share
I covered the part that could be triggering.
I am not a religious person. That night, the fighter jets kept bombing the city I lived in, ground was shaking and glass windows were shattering and no one knew whether the apartment block we lived in would stand up until the next day or not. My father told me again and again, there is nothing we can do, try to get some sleep. I laid down on my bed, still feeling numb, not knowing whether there will be a tomorrow for me or not and I slept. My body felt so heavy I couldn't even resist it.
This was the moment I was deeply, deeply humbled by my own mortality and how quickly life can happen in the blink of an eye. So small things matter. In fact, those are the only things that matter.
Making small things count is how you stay alive and then live some.
Whether this is a coup, a counter revolution, the 4th reich or an alien invasion, it doesn't matter. Keep an ear on the stories but keep every other resource you have focused on actual reality, tangible things that are happening. This is how you can make up your mind about what is the next important thing to focus on for you!
As of this moment, neither military nor any armed group has joined whatever this is, which is very very good. A proper coup doesn't give you time to prep, it happens overnight. Make this one count. "You still have some time".
The immediate danger to anyone in these chaotic days would come from armed groups or military. Since those are missing as of now, you need to focus on the next dangerous thing. For immigrant people as you can see it is ICE, for disabled people it is funds being cut off. Focus on whatever is affecting you in the immediate future and prepare for that.
The apparent lack of reaction from existing institutions and politicians is a good thing because if they were caught up in this mess, it would only escalate things and nobody wants that. The silence is the element of surprise here, since the perpetrators feeds of off rage. It is an attempt to de-escalate and establish inertia. Yet people shouldn't feel like they are left all alone and abandoned by their government. So there will be more messages released in the coming days encouraging people to unite and hang onto the shared sense of reality and normalcy to again strengthen the inertia. Do not leave your posts, whatever that is.
Disoriented nation needs to be stabilised as soon as possible. Help everybody else by taking care of yourself by being cool headed and continuing business as usual. Actions are louder than words, do not tire yourself senselessly in arguments, this isn't the time for talk anymore.

After the short term threats are mitigated you are now looking into the midterm risks. I think this is where everyone is struggling as it is not clear how fast things can go where exactly. The stories are now filling into this gap, stay critical. Adapt to the new reality as it unrolls, and don't rush to conclusions.
Trust the inertia.
Good luck.
