I find myself having to ‘dig just a little deeper‘ for the optimism I know I should have. I’m SO blessed it’s uncanny, I just have to keep reminding myself of this - the ole “count your blessings” analogy really holds. Slowly backing away from the news (that you generally can’t influence anyway), spending more time with music (who’d a thought, right?

), spending more time in the sun/nature, focus on your own brand of spirituality, and hanging with your ever optimistic dogs (cats?), family/friends - helps. Exercise also tends to help put things into better perspective. I’m trying to start an exercise routine next with a new (used) “comfort bike” for these aging bones (we’ll see how THAT goes)!
Like many things in life, I think you have to start with the mental toolbox that you’ve been given - to give you a hand doing what you already know will tend to help, or stopping doing what you deep down know doesn’t. If your own toolbox isn’t enough, seek additional help - there’s no shame in reaching out (even though men, in particular, generally really suck at this)! The “news” that I referenced above, states that depressive disorders are increasingly rampant in the general population. Stress takes its toll, in whatever form it presents itself (anger, etc.), and it tends to pile on top of other stressors - cumulatively it can cause real damage.
Take care of yourself my brothers and sisters, we’re all in this big ole world together - it’s important!
