Ryan,
It’s great that you’re talking to a therapist. It’s important that you also talk to your wife. You don’t have to accept loneliness when there are people around you who love you. Don’t think you’re doing them a favor by giving up on them. I bet your wife would be very happy if you just let her in and you could face problems head on, together. Sorry if I seem too adamant about your life. I am also struggling and just know what I would want from my husband. Let them be a part of your healthier life.
Hope
