Oh then yeah...
I wouldn't let it deter you though. You'll learn a lot about yourself. I got to the point where I would prefer to go places by myself. Everything in moderation though. I was out and someone gave me a hug I almost started crying. You never know how much these little things matter until you don't get them.
I thought it was just me, but we met these people in Greece and as we were leaving the girl was like can I have a hug? I said sure! And tears were welling up in her eyes. I wouldn't trade any of that time I spent traveling though. If you have the opportunity take it!
