I am all these things. I am too trusting because I want to feel optimistic and naive about people, because everyones different. This obviously does cause problems, but it is very good for friendships, as it means they are quite open and a lot more fun. I would also like to add that I'm also honest about everything, if I think something sucks but everyone loves it, I will tell them it sucks and sometimes it goes a bit deeper than that.
I think feeling socially inept comes from depression and anxiety a bit, where embarrassing myself is a big deal, so I over think things and that causes me to be clumsy.
