Freaking out

I just lost my job. I’ve been living paycheck to paycheck due to some past financial mistakes. I’ve been wanting to start a consulting business for sometime but have not been able to take action. I’m a bit panicked and overwhelmed. I have little savings and a family to support. What are some of the tools I can use to 1. Get over this panic and get to a calm place? 2. How do I get myself to take massive action so I can get a few consulting clients in the next few weeks? Thank you
