I think i have an obsession with video game girls, iin?

To make a long story short, I grew up being a hardcore Nintendo fan and when I hit the age of 12, I developed this obsession while growing up wanting to be with video game women like Peach and Zelda. When I got older, I drew pictures of me having sex with them, made stories about going on with them, and so forth.

What had happened is that when I turned the age of 19 and got a job, I still "kind of" believed they were real in a way. My co-workers sort of teased me about it, but I think they thought I was a little off in the head.

As I got older and faced reality, I started to get depressed that my hopes and dreams got shattered. The problem now? I have Post Dramatic Stress Disorder, meaning that I sometimes feel a little depressed about it, even though I know they're not real. I mean, I have a fiance, its just that it sometimes bothers me a bit once in a blue moon. I just had a dream last night that I was making out with Peach.

Should I see a psychologist? Or what should I do? This might have something to do with my PDSD because this hasn't been the only thing that bothers me a bit from time to time.

Thank you.

PS: I am 25 years old.
