One of the saddest things that I encounter in my ministry is when I hear Christians talk about being so "worried" about something. It saddens me because they have lost what Christ brings to our lives and that worry is counter to God's grace and embrace.
Christ in Matthew 6:25 says, "Therefore I tell you, do not worry about your life..." and we as humans have a very tough time doing that. It is natural to worry...it is not healthy to constantly worry about things. The problem with worrying is that we tend to let it consume us and control our actions. Christ is trying to tell us to "trust God" and not to worry, because when worry it consumes us and we loose the ability to enjoy our life and loose our connection with God.
If you are one that worries constantly, try giving what it is you are worrying to God in prayer. Christ says in scripture that we are to lay our burdens at the foot of the cross...that means our worries. If you can do that the joy of having Jesus Christ in your life will increase and the joy of just living will once again return to you.
But if you do worry and are struggling remember "I can do all things through Christ who strengthens me." Philippians 4:13
