Nope, I wasn't the go out in the woods for a week guy! I'm also not an introvert, if you recall, I have a similar habit to you in running out to every event I could get to! I did it because I wanted to build a life, I was anxious about being alone etc. and still am to some degree. I find it hard to come home at night to an empty apartment (aside from my turtle!) but recognize that I need BALANCE in my life. I do understand how being alone can be a deadly time if you allow it to be. I've set goals for myself for times when I'm alone. I do bible reading each night (or at least try to), I do some meditation each night. I allow my body to rest sometimes because it needs it. I used to ignore that and rush out to whatever was offered that evening. You need a tenor in the church choir, I'm the guy! There's a prayer group, let's do it! Bowling? Sure, I'm in!... I would refuse to listen to my body. Now, I do believe that you probably have a lot more energy than I, you're younger and seem to be extremely fit (good job, in that regard) but don't put asied that need to be alone sometimes, it's important. If you're afraid of yourself when you're alone then you're running from something, not to something. They say God often speaks to us when we sit down, be quiet and allow him to speak to us. Maybe just take a night and make it YOUR night to be with yourself and your maker. If you can't be alone then you're looking for R's that will provide that safety net and that makes for dependence on the other party and makes you more vulnerable than you need to be when seeking a R. Don't discard what others are telling you (and apparently it's not just me) as you're you and I'm me. Well, enough of my preaching...gotta run, things to do...things to do....things to do!!! have a great day.
