I’ve seen many people in your situation and it seemed to me the best option for most was to hasten slowly. Take some space to consider all options work-wise, if necessary see your GP and have some sick leave. Most GPs are sympathetic to these situations. Employment advice seems needed, either internally or externally, could you change to a different department or even work part time? Perhaps a financial advisor or a trusted friend to look at finances with you, talk to your daughter. You may have done some or all of these things, if so my apologies. Think forward, how would you like your life to be in retirement, a house move would fill space for months but what then? Would you like to work again or have a voluntary role? If you downsize would you stay in the same area and so have contacts and friends? I’m not being negative, just wanting the best thing for you. Take the space to decide, you’re worth some time, use sick leave if needed. If after thinking it all through retirement is the best option then go for it. I was an NHS employee, a different role but still stressful. I dug my escape tunnel and came out of the other side, meeting an an ex colleague some months later I was told I looked 10 years younger. I certainly felt it. Come back and let us know how things go for you. Wishing you well whatever your decision.
