I am not hopeful about our future. But something I came to terms with is that I am going to die. It might be in 40 years or it might be sooner, it could be next year. But it will happen. Also, it's possible that I don't just die but life becomes incredibly unpleasant. All the same to me in this current point in time, where I am able and I have means to do interesting things.

I know this is hand-wavy but I heard someone say something along the lines "we need to stop worrying about putting more years in our life, but work on putting more life in our years."

This sort of mantra helps keep me grounded when I'm deciding what to do with myself and my family on a day to day basis.

What I've found that helps me with this is follow through on the worry. For example, maybe I'm worried my boyfriend will leave me, and to follow through on that I think "then what happens?" Well, I would be depressed for awhile, and then eventually get over it. I'll go through the stages of grief for the death of the relationship but I will survive and move on. This Follow Through thought pattern works best on situations you have actual control over in your day to day life.

Another thought is "you can't control everything but you can control how you react to things".

I mostly use distractions as a way clearing my head.

The best thing to distract myself when I was really depressed was Geoguessr, it takes focus and is fun.
