Is it weird to not want to go places without headphones?

I was going to go to a new store today but I said I forgot my headphones. When I explained why that mattered I was told I was weird. Well, the new store was very overwhelming and I am pretty sure headphones would have helped. Also, I wear them all the time even in school I needed them for lunch/bus rides because all the talking overwhelned me. Especially at lunch with all the people, and talking, and smells.
