###Human: I feel like vomiting when I see dirty things or smell dirty things. Please help. ###Assistant: Hi. Your statement of 'I feel like vomiting when I see or smell dirty things and I cannot just sit with a drunk person' are commonly found in normal individuals and does not signify any mental or psychological disorder. But, your statement that you canceled your official trip because of this issue signifies that you have attached too much significance to a trivial problem. At this moment, it seems that your thought process is dominated by ideas of vomiting and you are not able to get rid of this. It is also possible that you are aware that these are not rational ideas, but whenever you try to resist, you get rebound anxiety or increased anxiety or more vomiting feeling. If you are wasting more than one hour a day on these ideas and that is impairing you in your occupational, academic or social life, this can be due to obsessive compulsive disorder (OCD). In this disorder, people are very particular in regard to cleanliness and not able to stand slight dirt and have a tendency to wash their hands multiple times. I assure you that this is quite treatable and a lot can be done to improve your thought process. This disorder can be treated with medication or behavior therapy or a combination of both depending on the severity and response to a particular kind of therapy. At this moment, I suggest you consult a psychologist counsellor online. --->
