I'm a single parent of one, never married. Aside from a few 6mth relationships I've had nothing long term in 10yrs. I have a high income and work comes with its stress but enables us to have a decent house, holidays etc. I'm on holiday abroad at the moment with my teenager who is lovely but I don't feel any joy. I'm not in the moment, just going through the motions. I'm tired, anxious about what's going on the world, and struggling to summon the energy to make the most of our time together. How do people with a positive mindset shrug off the mundane to really enjoy life? I'm turning 50 and feel like I'm a miserable bugger who can't be much fun to be around. I miss my carefree 20s. Is it normal to feel like this? Is it just part of getting old, menopause and the general burden of responsibility? I eat healthily, exercise and am not depressed, more discontented despite knowing i'm in a far more fortunate position to many others and should appreciate what i have. Any tips to snap out of it?
