Ok, so you've lost your job and don't know what to do.
The primary thing to do is not panic and to begin preparing, actively applying and update your resume and cover letter for roles.
Keep your options and opportunities for jobs open. Think carefully about your skills and experience and what you can do and are willing to do.
Even though jobs can be scarce during periods of low economic activity, you need to stay positive, in control and focused.
To get things moving with your job search, maybe utilise the services of a professional resume writer so that you can get your CV and cover letter in order, ready to go.
Don't rush your applications, as employers do notice this.
