I hear what you're saying about your distaste for the 'lone wolf coder' role but you can use your skills and experience to hit the ground running instead of hunting for jobs until you catch one. The networking advice is all well and good but it doesn't pay the bills and it's not a quick fix. You network so that you can call on your contacts in times like this, starting now just delays the payoff and poisons your interactions with dread that you have to hit them up with your plea sooner or later - or worse, right off the bat. Networking is about building a rolodex, give and take, but mostly building relationships. If you need something right away it ruins the premise and people can smell it.
My advice is this: Philly must have coworking space. That will solve your 3 problems. You can be with people. You can help them, and receive help. You can advise, consult, contribute. Make money, join the community and networking will be a part of your life. You can hunt for a job for a few hours a day, but help people and they will help you. You'll become a part of your new home, and your new life. You may even like coding again.
