Please don't isolate yourself right now. This may sound silly, but take a walk around the block at least once a day and say "hello" to every person you pass. It's a simple thing to do, but you may not feel like doing it right now. But that means you NEED to do it. Trust me--You will feel better by the time you get home. You'll also start running into some of the same people whom you'll eventually begin talking to. Please do this for yourself. The Lord will be walking with you.
