My body is not functioning anymore

[Nathaniel]

Has anyone else ever experienced intense physical symptoms, yet you're being told that physically you are completely healthy?
I have been suffering from sudden bouts of vomiting for the last four weeks, with no apparent physical explanation. My doctor strongly suspected an ulcer but all tests were negative. A slight vitamin b12 deficiency was the only thing noticeable, as well as my body temperature being slightly beneath normal.
I am being told that physically I am fine but almost every day I feel extremely nauseous all of a sudden and I always end up vomiting. It does not seem to be food related since I have no appetite anyway and when I throw up it is mostly water, acid and bile (sorry for the grossness).
Antihistamines sort of help but they make me too tired too function.
My doctor suggested that it is stress related. This is not helpful at all since I am already forced to take time off work due to corona. There is no way I can reduce the stress any further. What I need is a way to make my body function normally again.
Any advice I'd really appreciate.

Unfortunately we can’t give out any medical advice.

Is there any chance you can see another dr and get a second opinion?

Have you tried meditation or relaxation techniques? If not it could be worthwhile trying every day for an month to see it could help. It takes several weeks to make an difference if it's stress hence why I suggested an month.

Otherwise like the previous poster said it may be worth asking for advice from a second doctor.
