I think I'm having one.
Turned 50 last year and the last few months have been a struggle. I hate this time of year anyway and have always suffered from SAD but this is deeper. I Googled 'signs of a mid life crisis' and these came up:
Feeling apathetic, numb, or generally 'blah' about things in life
Pervasive feelings of unfulfillment or emptiness in life
Feeling trapped in your life
Frustration and irritability with work, family or self
Becoming withdrawn
Lack of purpose in life
I don't think I'm depressed (been there in the past and this feels different) and I'm not about to go out and buy a Porsche or run off with a 25 year old bimbo. I don't drink and I keep relatively fit but being in the 'sandwich' generation with annoying teenage kids and ill elderly parents is hard.
Is it just a BS term or is it a real thing? Just wondered if anyone on here has been through it and how did you cope?
