Do it quickly

One of the worst things in life is to be dealing with an issue that seems like a leech. Some things are so important to us that, even if we want to let them go, they stay attached and steal our thoughts and energy. Maybe a leech isn't the best picture, that's gross. Let's call it a band-aid. You've been hurt, and it's ugly, and you don't want it to get infected and be uglier, so you put a band-aid on it. It helps, doesn't it? It doesn't hurt as much when something hits the wound again. But I think we've all had the experience of leaving a band-aid on too long. Your skin gets all soggy and gross. Eventually you have to take it off and let the fresh air do it's work of true healing. Worst part: if it's a really good adhesive band-aid, it hurts to take it off. So the best plan is to rip it off quickly, so it's over quick and the healing can begin.
This is a good analogy for those problems we have that wound us. Especially relationships. I know it's something I talk about a lot, but it's one of my favorite subjects in life. Once I even used the band-aid analogy with a friend who went through a somewhat unexpected and painful breakup. With the wounds that cut the deepest, we always seem to want to take the band-aid off slowly. It may seem nice to go through the exposing process bit by bit, making sure to let go slowly so we don't forget anything. But at some point, we have to just rip it all out, trusting that God will heal us and that (in this life) we'll always have a scar to remind us of the experience, whether we'll look on the scar kindly or with sadness.
It says in 1 Peter 5:7, "Cast all your anxiety on him because he cares for you." My Bible professor made an interesting point in class the other day. In English (and this is the case with many words, which is why translating the Bible is so difficult) we only have one word for that sentiment, "cast". But in Greek, there are two words. One means to cast as in fishing, with the intent of reeling something back in. This is the meaning we humans like to use when we're giving our problems to God. We say that he can have them, but we keep a hold on them so we can check up now and again. It like ripping off the band-aid and putting another on as soon as you're done. However, the word used in this verse means to get rid of permanently. To give the issue to him completely, and trust him to take care of it and give us healing. This is the way God intended it. He didn't design us to carry open wounds. He designed us to heal and carry scars. Like a plant with dead branches that still bears new growth. 
Maybe it seems like we have to bear our own burdens, but God is fully willing to take them from us if we can only learn to give them.
