Who can I talk to?

Sorry if this has been posted before, I've just registered and was seeking advice.

I (21 Male) was diagnosed when I was 5 and my whole life I have been in the closet about my Aspergers. I have been quite successful at hiding it, altough it wasn't until the past few years that I have started to fully grasp the extent of my symptoms. I've never recieved any form of help for it since early childhood, although since becoming an adult I can see that I am struggling. I was just wondering how I could find someone to talk to about it, or if there are any services out there that could be useful for me. Cheers.
