I got fired from work and i have a $9000 credit card debt

Hi,

I got fired last week. My weekly gross income was $1450. I am 27 years old, living with my parents. And I have zero savings (I used up all my savings to pay off my car 1 week before I got fired)

My 401(k) shows a current balance of 28k and a vested balance of 16k. I got this from a mail

My ESOP shares show a current balance of 6k and a vested balance of 3k. I got this from a mail

I already filed for unemployment, applied for Medicaid (since I lost my medical/dental/vision insurance)

I've been applying for jobs, but so far no one has reached back to me.

My uncle asked me if I wanted to work for him for the time being. He offered to give me $ 1,000 per week in cash until I hear from employers.

Questions:
1. Should I email the previous HR and ask them how I can access my 401 (k) and ESOP shares? The mail can come from the financial institution that handles both 401 (k) and ESOP shares. When I was working for that company, I forgot to make an account

1. Once I get access to my 401 (k) and ESOP shares. Should I take out some of it and pay my credit card debt? Or don't touch it.

2. Should I use the COBRA continuation coverage for my insurance, or is it not worth it?

I'm estimating $600 weekly from unemployment for 26 weeks and $1,000 from cash with a total of $1,600 per week / $6,400 per month

These are my monthly expenses:
1. Internet = $100
2. Car insurance = $200
3. Phone bill = $150
4. Gym = $50
5. Misc = $75
