Feel the need to act exactly like my favourite characters

Hello everyone. This is Crazyhyena948 and it is my first post on this site. I have Aspergers, ADD, hypochondria, OCD and several phobias.
This is about something I didn't use to consider a problem but which I have now realised may well count as another of my damaging obsessions.
For some time, I have had the tendency to so strongly indentify with fictional characters who remind me of myself (in appearance, personality or both) - especially cartoon or other animated characters - that I feel like I NEED to justify having this connection by acting exactly like them but without making overt references (unless I feel like it). Often, my mind becomes conflicted: one moment wanting me to "stay in character", the next moment deriding me for not being my true self, while at the same time I feel like I don't actually know what my true self is anymore.

An example of how this can distress me is when I got reading glasses. After I was prescribed them, I was at first happy as this meant I was even more like my favourite characters who wear glasses (e.g Filburt from Rocko's Modern Life) but then I became upset because I was then unlike some of my favourite characters who didn't wear even reading glasses. I had to look up Ren Hoek wearing reading glasses to get the feeling that i could never relate to him off my chest.

I guess what I want to ask is a few things: is this common? Do others on this site have similar obsessions? Is there a way to deal with them?
I definitely want to continue being a little obsessed with my favourite characters, and even occasionally fantasise that I am actually them, but not to the point where it overshadows my life.

Any replies and suggestions anyone might have are entirely welcome.

Dear Crazyhyena948:

A whole lot of my life I pretended to be somebody else, sometimes taking on a certain way of walking, taking on the air of someone else, someone important, successful, a Somebody. I was rarely myself, as myself meant someone so very scared and so very sad, so i pretended to be somebody else.

It is recently that I find myself... being myself.

I used to smile and feel it was a fake smile, and I guess it often was. I hate smiling still unless it is an authentic smile.

I used to feel I was so flawed, so inherently wrong, bad that I was afraid to ... be me. I no longer think I am flawed (what a revelation that was!) so I am not so scared anymore to be ... just me.
