Complicated Situations

How do you deal with problems or issues that pop up out of no where and you have no idea how to handle or deal with it? It is always really hard to deal with because you just have emotions running and thoughts going a million a minute but sometimes you just need to stop and relax, realize everything happens for a reason, and deal with the situation your dealt with. There is always a reason we go through the things we do, we may not know why right now but eventually it will all make sense and everything will always be ok. Even if it doesnt seem that way it will be.
