ADF is teetotal so don’t worry about him going out on a bender.
Although what KB says, regardless of what the pint is of, is sterling advice.
Small things in your everyday life will pile up against you, bit by bit, stupid inconsequential problem and insignificant irritating thing, one on top of the other, until the weight of it is slowly, imperceptibly, grinding you down. You need to do something to challenge, excite or just please yourself. Get a date on the calendar to look forward to, a meet up with fellow car/cat/cardigan enthusiasts, whatever. PM one of the guys on here you can relate to and say ‘Hi’ or start a ‘who is dropping by x location?’ thread and see who can drop in.
If it’s ‘just’ a headache think if you have done anything different lately, changes in routine, increased use of mobile device (pecking away with one finger!) reading, extended computer use, forgetting to use your glasses, etc. They can all trigger something. If you wear glasses when we’re they last checked?
If we have nothing above working then off to the quack, if you give them a call tomorrow you might get an appointment this side of TDWSNMUMD.
Get well, stay well, we all need you around here
