Yep, this is the best way for you to begin actually, considering you cannot isolate one incident just yet. One will always come to the top of your mind though, which is usually the suspect that needs to be hit first. Please keep going, because your definately on the right track. Oh... just be warned and prepared, you will get ill from doing this, have no doubts... expect it, don't fight it, but remember to bring yourself out of it again because it has huge benefits in a few months for you, and you will find you will begin to feel less anxiety and stress over all these things.
