https://spokengoods.com/ - a podcast summary site that also pulls out product mentions. I kept forgetting which books were mentioned while I was out doing stuff.
Feeling Good and/or Feeling Great by David Burns. It should be on everyone's bookshelf, imho. It has the exact step by step process that you're looking for.
I would focus on the games first, and then spin up the LLC if one of them takes off. Otherwise you just have the maintenance and fees of the LLC which is a distraction.
Be an organ donor. Donate blood on a regular basis. Skeptoid had a podcast today that talks about blood donation with some interesting tidbits about shelf life of platelets and whole blood. (5 days vs 42 days)
Consider activities that broaden your perspective, e.g. reading a biography or travel somewhere.
Consider journaling deeply about areas that trouble you, whether recent or distant past. Also consider journaling in detail about the best possible outcome for yourself. Forcing yourself to organize thoughts in writing can help understand confusing situations.
If therapist isn't working, find another one. It's totally normal to try several.
During this period of tech layoffs I just wanted to highlight some research done 30 years ago which is part of a larger body of research around expressive writing. My apologies for re-wording the title, but the original paper and the linked-to summary have vague / convoluted titles.
Pretty much everyone in a developed country. Just zoom out your time perspective. I'll go ahead and say paramedics, but there are examples all over the place.
Language is not precise, and companies define their roles differently for a variety of reasons, including the nature of the business each company is in. I'll take a stab though.
In general, "salesperson" implies a single transaction. You go to the Apple Store, you talk to a salesperson, you walk out with a big iPhone and a light wallet. Note that Apple calls them "specialist" or something, see point above.
"Account" implies an ongoing relationship with a steady stream of transactions, such as an advertiser with a large account on an ad platform. The account manager's role would be a) make sure to keep the account and b) find ways for the account to spend more money in a way that's beneficial to both.
Account executives typically sign new accounts, so they are overall selling the value of the ongoing stream of transactions.
Further muddying the waters is that all these roles are under the "Sales" org, so you could arguably say an account manager is in sales even if they're not a salesperson you meet at a retail store.
I wrote a simple stopwatch menu bar app called Mini Time Tracker [1] for Mac. I use it to track how much time I do a single thing, e.g. coding. It's like pomodoro in reverse and only stops when you tell it to stop.
You might find the concept of Ikigai interesting. Also, Arthur C. Brooks recently wrote a book, From Strength to Strength. I think his audience skews slightly older than you, but it's about how people find meaningful second careers by leveraging the wisdom they have gained in their first career.
Just my opinion, but there are tons of ways to find meaning, e.g. advising startups, angel investing, teaching, giving talks at your alma mater, generally helping people in different ways. It's not for everyone, but lots of people have kids and find meaning through them. You can also do stuff for your parents. Looking back on it, I wish I had just paid for a home improvement project at my parents' house rather than simply suggesting it to them and hoping they'd do it.
What if you turned it from a solitary activity to a pair activity. e.g. ask a trusted peer to take notes as you explain the design of your system with whiteboard. Then clean up the notes and drawings. The peer could also point out issues or common questions in real time allowing your doc to address them proactively.
The Body Keeps the Score lists a variety of therapies, and trigger warning, contains details about traumas of people the author has interviewed. Good luck.
