Things don’t always work out as planned. In fact, things NEVER work out exactly as planned. So, if you are thinking life is not fair or life doesn't make sense and that this is a good reason to use, then you are not being entirely realistic. You are asking for more than what life can give you. It's OK to make plans, but you can't be God so you can't control the results. Trying to control results and people causes frustration, anger, fear, and resentment.
TODO: To feel better, have faith that your loving Higher Power has a better plan for you; it's just that you may not be able to see it yet. Remember your concept of God does not have to be a traditional, religious concept (although it can be); God can be any positive, healthy force you want that helps return you to sanity.
