I was dreading retirement, as my last job, which I held for around 9 years, was the best job I ever had. I so wished I had gone down that path years before, instead of flitting around for a few years in various jobs. None of those other jobs were fulfilling at all. So when I knew retirement was looming, I became quite despondent. I did an extra year, and left at 67.
The first two years were very trying, I felt I had no direction or purpose. In my job, I was fairly well liked, my opinions were respected, and I know I worked really hard, and helped so many people.
I was going to go back as a volunteer, but I couldn't face not being one of the regular staff, and being excluded from the inner workings of the whole organisation.
So it has taken me a couple of years to accept this different lifestyle. But I have got there. We have a lovely touring caravan, which we use regularly throughout the summer.
The winter is a lot harder, but we have regular family contact, occasional grandparent duties, I go to the theatre with my sister once a month, watch some good series on t.v. etc.
So my advice would be to give yourself time, don't worry that you don't want to join clubs, groups, ramblers etc. As time goes by you will find your days getting naturally fuller, as you start to read those books you never got round to, you perfected the craft you kept abandoning, you chatted to the neighbour you had only been on nodding terms with.....before you know it, there will some sort of settlement and acceptance of your daily routines and work will be a distant memory.
So just give it time, don't be too anxious about being discontent initially, it will all evolve and you will be busy with your own daily activities. Good Luck!!
