I graduated in May with my ADN/ASN. Got my RN license in August and I was working until August. I haven’t worked since then as new grad. The reason why was I was going through personal issues. Im planning on working in March would that be an issue ?

If you are planning on acute care I recommend you request to reenter as a new grad and have a complete orientation to cover areas you may be weak or unfamiliar with.
Many hospitals now offer internship programs.
If you have a specific area of interest apply for it
Talk to a counselor from your school, they can point you in the right direction
I hope you are doing well.
Sending strength and self confidence to move forward
