An ounce of prevention is worth more than a pound of cure. Get rid of the isolation and your brain fixes itself so that attractive and less needy behavior is more automatic.
Lots of people are busy and work remotely, but they still make sure to go out every weekend to cold approach, join hobby groups, build social circles, build community, etc. Your isolation was, in many ways, a choice. You chose the easier path to remain isolated over the harder path of taking more social risks. Or, if you really really couldn't think of any other possible solutions to escape isolation, you still could have come here to brainstorm solutions together. Dating coaches like me surgically break down clients' schedules all the time in order to find opportunities to habit-stack approaches and other such social/seduction opportunities. And even if you get too busy to go out at least once a week, having even just one regular partner for sex will still help balance your brain chemistry so that you don't act like you did. Focus on the fundamentals. Think about what you're avoiding, and do those things.
