I've gone through similar things where it seems like my emotions are controlling my decisions (usually in bad ways). The only helpful thing I can say is that learning to separate feelings from my decision processes is the best thing, but still a challenge. It's difficult to find a balance. My tendency is to go from one extreme to the other (all emotions on or all emotions off). So what I TRY to do that seems to work the best is stay in touch with my feelings and acknowledge them and tell myself it's okay to feel that way, but to not let my emotions control me. Remember you are not your feelings. They don't define you. Just because you may feel like--for example--a failure, doesn't mean you're a failure. So ignoring your feelings will definitely cause problems, so stay in touch with them, but take a step back from emotions when making decisions. Good luck.
