I Believe In Sending Positive Vibes

Think I need this more ,don't think sending many a lot of people seem miserable around me or could it just me being paranoid not sure if it's my influence or what but my friend use to be a lot happier we still talk a lot and still hang out at times but I don't know just doesn't feel same .I don't like I don't like sending negative vibes sometimes one of the reasons I can be quiet need to be careful make sure I am not sending positive instead of negative .
