I have had this problem off and on, but I have noticed that when I get really upset (like earth-shattering upset and stressed), the next day I'll have bloody stool. At times, it's as if it is pouring out of me. It is much worse when I have really frantic episodes the day before. Sometimes any little thing can upset it. Also, my head will fell like it is going to explode. Sometimes it's like my head is running away from me or detached from my body and likewise, my body aches terribly. Is this just stress? It can get to a point where I feel rather impulsive and quite anxious. It ranges from temporary discomfort to feelings of terror. The psychological symptoms are bad by themselves, but the physical discomfort and fear I feel from the bloody stool, only seem to make me worry more. What should I do?
