What and why are you afraid of? The World out their is Beautiful and so are the people. Go explore because you know you can :)
Let me give few tips about why you shouldn't be afraid to travel alone: 1) You can plan the trip the way YOU want to, without any dependencies. You have the freedom to do exactly what you want to do and that's all the more fun :D 2) By arranging everything on your own, you're going to increase your self confidence and as well as the sense of responsibility. 3) First try out with a commercial place where you know, you're not alone. Eg: Dharamshala, Jibhi, Dalhousi, Bir and etc. 4) I know making friends out there is not everyone's cup of tea. So what? Try and book your trip with a bunch of people/groups that are offering very good packages online. Search them out on Instagram/Facebook/Google. Since this way, you are definitely not going to be alone and will have lifetime of memories with new bunch of people and friends. 5) If you are not comfortable going with tour leaders or groups, you can book your own stay in Hostel, Zostels and etc where you will meet people like you from different parts of the world. *Look, their would be million other opportunities and reasons of why you should travel alone but their would be just ONE single reason that is stopping you to go ahead. So you gotta choose the right path on your own* Once in life, Go wild :) I hope it helps!
I too was having same fear one year back but after my first solo trip to Rann of Kutch I changed my opinion. Frankly to say now I enjoy travelling solo. So go ahead and experience it. Happy travelling!
Everyone's scared to travel alone until they do it. And trust me, once you travel alone, you'll never want to travel with anyone else. Traveling alone gives you a sense of freedom and independence like nothing else can. You obviously have to be careful and constantly aware of things when traveling alone, but that's a good thing to practise in general anyway. :)
