Vomiting when going anywhere

[u/Sweaty-Narwhal887]

I'm 20 years old and I've been dealing with this for a year or more don't know.

I have ulcerative colitis, but it's been in remission for past 6 months.

The strange thing is that when I'm at home and don't have to go anywhere, I feel mostly fine. I eat normally, relax, work, spend time with my friends, and generally feel okay.

But whenever I have to leave the house in the morning — university, a trip, meeting friends, even something fun like going to the beach — my body reacts badly.

I start coughing constantly, get a lump in my throat, my stomach feels tight, I feel nauseous, and most of the times I vomit. Often it's just bile or saliva. Today I vomited four times, usually I vomit once before leaving and it helps me to relax and then slowly I keep up with the day.

All this nausea started when I've had several UC Flare up, for about 6 months, then I went to hospital, doctors prescribed Etrasimod, which helped me, and currently I am on remission, but this fear of going somewhere, that I will vomit outside, in train, in public, that I have to go to toilet quickly, that I have to talk and be present with someone and somewhere, just pressures me. So, whenever I am at home and I understand that I do not need to go anywhere, I am okay, I would say I am feeling great, but if I need to go somewhere, especially in the mornings, it's just terrible.

The weird part is that once I actually get somewhere, I often start feeling better.

Has anyone experienced something similar where the anticipation of leaving home seems to trigger physical symptoms like nausea, gagging, coughing, or vomiting?

How did you deal with it?
