Sometimes when we're trying to pray, we might feel like we're not good enough or important enough for God to care about. But that's just a temptation, it's also an insult to God who created us and loves us as we are. When we're thinking that way, we're not really turning our minds towards God but towards ourselves, instead of remembering that God's promise is to answer us when we call on Him. We would do good to remember that Jesus showed us through His actions that He cares for everyone, no matter how insignificant we might feel, so when we feel like we're too miserable to pray, we should turn to Him and ask Him to heal us too. He's waiting for us to ask.
