Benefits...

After getting medically retired by the NHS, I currently do 1 days work a week, outside of the NHS. I receive an NHS pension. I am currently struggling in work doing the 1 day. My question is, if I give up work will I be able to receive any benefits? I have applied for PIP, but will I be able to receive any ?ESA or ?Universal credit for example. Any advice greatly received. I am married, and my husband works full time. Live in the UK. Thanks in advance....
