I have a slightly different experience to many of you, when DH Retired at 65 his health was poor (depression) so when the opportunity came for me to take Early Retirement a few months later at 50 I jumped at it. We had a large house & garden so spent time getting ready to downsize. I put a lot of research into our chosen area. Everything happened in a rush when the house went on the market,, within 8 weeks we had sold, bought in our chosen area & moved.
We settled into our new home, approx half way between our DDs (1 his, 1 mine). Unfortunately DH developed Terminal Cancer & was admitted to Hospital 11 months after we moved. I was left on my own & after about 9 months put my house on the market, took me 14 months to sell (cash buyer who wanted to move quickly). I went to stay with my DD for 2 weeks then a Holiday Flat until I could move into my new property about 10 miles from my DD, her OH & 2DGS.
Moving again has meant I have had to make new friends & explore my new area. I have lovely neighbours, joined a couple of Meet Up groups. I enjoy the freedom of Retirement, go out, stay in, read, see my family & fit in visits to my DM who lives 300 miles away & at 88 doesn't travel any more.
My advice would be sort out your move making sure you're in the right area & check out activities, volunteering etc. Good luck
Life doesn't always work out as planned, I'm glad I Retired when I did, I had almost 7 years with my DH which I would have missed if I'd worked until Retirement at 66
