Yes, the anxiety at the beginning and lack of purpose was strong, but over time it has faded and now I am used to the lifestyle and make my own purpose. I do plan to contribute more to society in the long term. I want to eventually start my own research institution (if algo goes bonkers). Algos do add liquidity to financial markets and help prevent bubbles like 2000 and 2007 from forming through greater market efficiency as well. However, right now I'm still enjoying my "rest" phase as the 8 years before that were not fun, long hours, long commute, so I don't feel bad about getting some break.
