Five things you HAVE TO do today.
Make or plan a 'Go Bag'. Get a bag, one for every person in the house, with essentials. Clothes, cash money, snacks, bottled water, mini-first aid kit, tampons/pads if you need them, socks, a trash bag, hand warmers... There are TONS of YT videos going over what else you might need, so look it up. The goal is usually to pack enough for 3 days of being on the road. If you can't make it today, you MUST make it by the end of this coming week. (This is also good practice in case of other emergencies, like if you're ever displaced or have to travel suddenly.)
Get the phone numbers of law enforcement and a lawyer. Go to city hall, or go to their webpage, and write down the number of the chief of police. ALWAYS CALL 911 IN THE EVENT OF AN IMMEDIATE EMERGENCY. Make sure you label the names and information to contacts. Find a lawyer for your situation-- Criminal defense, civil defense, divorce attorney, immigration lawyer, etc.. Start familiarizing yourself.
Begin the paperwork to get your passports, DL renewals/issues, SSID copies, birth certificate copies, and State IDs. We have a foreign immigrant who's got copies of our federal information, we have got to have physical proof of our identity even if you do not plan to leave the country. Passport photos can be taken at many different locations, and in some cases you can take them yourself. This link is for online renewals, HOWEVER it shows you what quality photos are acceptable and which ones aren't.
Get your finances in order. It's Sunday so the banks are closed, but draft a plan and CALL TOMORROW. Take care of your debts as much as you are able to. Look into small, local banks where you can walk in to withdraw your money.
Do one kind thing for yourself today. Have a beer and watch a movie, follow along with a YT tutorial, have a spa day, meditate, go for a walk. Do something to benefit the soul.
