As part of a Bible study that I do a few times a week, I read This Devotional on Our Daily Bread's website and it opened my eyes to something I have already realized multiple times!
I know that I can "cast my burdens on Him" and that there's no need to keep wallowing in my sorrow, but I keep ignoring this fact.
The times when life feels extra crappy are usually the times when I have drifted from the presence of God. If in his presence is where we find peace, then when we excuse ourselves from His presence...of course we're going to be worried and feel overwhelmed all the time!
I need to get and once and for all keep this in my spirit. Once I start feeling like life is getting to much to take, I need to "lift up my eyes unto the hills from whence cometh my help. My help cometh from the Lord which made Heaven and Earth" (Psalm 121:1-2)
