Christianity isn't a boxed-in, boring life of can or can't do's. It's a life filled with blessing when you realize who you become in Christ.
The steadfast love of the Lord never ceases; his mercies never come to an end; they are new every morning; great is your faithfulness. Lamentations 3:22-23.
The sleep of the working man is pleasant, whether he eats little or much; but the full stomach of the rich man does not allow him to sleep. Ecclesiastes 5:12
And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. Phil 4:7
Moods and feelings will repeat themselves, but if you bypass them and go for it (whatever that "it" is), you'll be a step closer to where you want to be.
