Bad day

Today I feel unequipped. I feel like I just can't do this; motherhood, homeschooling, life. I feel like I'm so lost, a failure. I guess that's why I'm not supposed to go on my feelings, right? If I went on feelings, I would have quit a long time ago. I know God promises to never leave me; He says nothing is impossible with Him. I know His promises are true, but today I don't feel like I can do it. I know with Him, I can...because the Bible says so. But right now, I just don't know.
