I am sure this is an issue that many Christians experience: Sometimes, you get sad over trivial things, such as your possessions, hobbies, or your general way(s) of life. I know that we are commanded to "Repent ye: for the kingdom of heaven is at hand. (Matthew 3:2 (KJV))", but I find that to often times be pretty dang difficult, and I do not know why I keep experiencing these feelings of general sadness, even though there's nothing to be sad over (*other than the biblical doctrine of "being tried with fire"*).
Any tips from any of you all to help get rid of this general feeling of sadness (Or at least... to kind-of suppress it)?
