Sorry you get so upset but its good you realize this isn't good. Do you have a therapist? I also hate being disturbed when I'm trying to sleep. Although its good to let things out, the key is to find a better way. Next time you feel it building - try going to a quiet place and do this breathing exercise - inhale deeply using your stomach muscles and hold for a few seconds - during the hold, quickly tighten all your muscles. As you exhale slowly, relax all those muscles and you'll feel the tension melt. Keep doing the slow breathing/ tightening then relaxing muscles until you feel more calm.
