Thanks for providing more information.
Well as you have frequent episodes of diarrhea, feeling nausea and now dizziness,sweats so your symptoms shouldn't be ignored and it's not advised to travel in such conditions.
You may possibly have Gastroenteritis and now dehydration due to fluid and electrolyte loss.
Other possible causes may include Colitis, Intestinal parasitic infection.
Even your blood pressure should be monitored and you shouldn't take your ant-hypertensive medications without monitoring your blood pressure.
It may be possible you have low blood pressure, low blood sugar levels now.
So having said this, you need to be see by your regular doctor ASAP and injectable medications along with IV fluids should be given promptly.
If possible visit ER.
I strongly advise you shouldn't ignore shortness of breath.
I hope this helps.
If you have any further query then feel free to ask.
Positive feedback and bonus are highly appreciated.
