Buying property in UK and working here until 67 as no jobs at home in Ireland for my age

I am 58 with almost no private pension as I worked agency as a mental health nurse a lot of the time due to being a single parent. I have a masters degree in family therapy. There are no jobs in this in Ireland. I was working privately in Ireland in family therapy and nursing before I moved to the UK last year. I found I could no longer do 12 hour nursing shifts.

I moved to Newcastle last year and got an 8a Grade in family therapy and renting in Newcastle.. I am downsizing my house in Dublin as it needed a lot of maintenance and was way too big. My children are grown. I was left a small cottage in the countryside in Ireland by my uncle when he died 15 years ago, so I do have a base there (650 sq feet). but in a remote rural village and not near any jobs. I will retire there though.

I would love to move back home to Dublin but there are no opportunities in family therapy - private work isn't reliable, and I need to work at least part-time until I am 66. Ireland is quite ageist even in jobs like supermarkets, coffee shops etc.

I would love to buy a small terraced house in Dublin with the money from the family home, but I also can't see myself being able to go back there to work before I retire in eight years time. If I buy in Dublin, where my heart is, I will have to continue paying rent in the UK for the next eight years.

I intend next year to look for jobs around Manchester and Liverpool as I have family there, so would buy there if I was going to buy in the UK.

I would appreciate any advice/comments on my dilemma - is it worth buying in the UK as I will be here at least for next 6 to 8 years. I hope to go part-time as I think I will burn out if I continue working full-time as a family therapist - it's intense. I couldn't afford to go part-time in the UK unless I had no rent here. I feel scared about being 58 and not getting other jobs, but the NHS seems to be the only place that isn't ageist.
