Moving to UK , i am a female 60 years old and I would be looking for a job, what would I be entitle to ? moving to UK , i am a female 60 ye?

I am a female 60 years old moving to UK and I will be looking for a part-time job, I am from a E.U.country, 2003/ 2005/6 I worked in Uk and I was paying stamps, also I never claimed anything and I dont want to claim anything but my worry is that I am on medication for life and my question is really, would a 60 years old be entitle to free medication although I would be working part-time as I am aware at my age( 60) it would be difficult to secure full time, job, oh I forgot to mentioned also that the reason for moving is cos all my adults children are working professional in employment full time UK after finishing their masters degrees in our own country and I miss them very much and the little grandchild too as i am the only one left here and feeling extremely lonely without them, thanks in advance for information.
