Some things that have helped me reset in the past:
• the easiest way to make friends is to go volunteer somewhere. doing hard things with people is the only way i've found to deepen relationships. you will want to hang out with people you've picked up trash with, but maybe not folks you've played pickleball with
• block your phone from everything for 30 days: https://shiftyourphone.com
• spend 12 hours bicycling in one direction on Saturday, and then bicycle back home on Sunday
• no booze, no weed, no cigs
• it sounds like you also want companionship. the way to find a life partner comes naturally from the other things: making deep friendships via volunteering, resisting the algos, being healthy, etc.
• all of these probably require energy that you don't think you have. set a 5:00am alarm and your brain will eventually accept that your body wants to do the new thing
