Coping with retirement
I retired 1 year ahead of mandatory age.
Prior to retirement, i had my share of concerns about how to occupy my time after having worked 35 years without a break.
I guess it is important to just tell your mind that things will work out. Meanwhile reach out and talk, even with strangers at the shop, pub. It helps to see how others cope. Just don't stay at home... reach out and do anything to be occupied.
I managed to recently start a new job nearby and the social interactions really help.
