You don't have to panic. I had also problem like this.But it is gonna be okay.Your first solo trip will be a different experience for you.You will learn life like a pro.Trust me.All the best.
Make the best out of this trip because you will remember this trip for the rest of your life, rather than panicking try to imagine how beautiful the place is going to be.
Hi Ishvani, I felt the same before my first solo trip. It is quite common. Just look at the pictures of the places you will be exploring very soon. Do some research and find nice restuarants, cafes and bars in your destination. Read other solo-travellers experiences who visited the same places. These things will motivate you and you will feel less anxious. Do write on Tripoto about your first solo trip experience. We'd love to hear from you.
Do not panic.... Because when on roads you need to keep yourself cool.... And communicate on road as much as you can.... And do the research about the place beforehand...
Believe in yourself and just do it. best of luck for the trip. I was also in same phase means on my solo trip for hongkong. But believe me it was best trip and when you will back u will be feel the same. just keep some distance from dark place after sunset and be active in every mode.keep some packed food with you will help a lot.
