I think I have adult ADD

[SilentLoner]

I'm feeling very frustrated as I type this.

I've always been a procrastinator, waiting until the last minute to do things but managing to do fine grade-wise, this inlcudes essays, midterms, projects, etc. So I've become used to it.

This semester however, I'm in a difficult biology class that requires a lot of studying during the week. Long story short I think I'll be lucky to have a C in the class, thats my average at the moment.

I have the second midterm for this class am almost unable to study for it despite doing nothing else all weekend. Last night I actually started crying out of frustration - I stare at the pages and try to answer review questions but my mind jumps around like there's no tomorrow. I got myself to focus somewhat by punching myself very hard in the limbs when my attention wavered.
I feel like I need to get up and move around every five minutes. I browse online with no point even though I have nothing to do online and am bored. When not online I daydream constantly.
This has also prevented me from studying during the week like I should be.

In desperation I looked up some online "do you have add" questionarries and I seem to fit a lot of the descriptions and the tests suggested I might have "moderate" add.

I know add has a high comorbidity with anxiety disorders. What should I do/ I've mentioned this to my mom but she just scoffs at me and says "we all have "add" to some degree. Deal with it."
(She's been like that with my SAD for quite some time as well).

Her reasoning is that I sit through films well and like to read. That's true, but I've read that a lot of people with ADD can sit though things they enjoy. And I like going to the theater but once I get the film on DVD, I'm constantly pausing, fast fowarding to parts I like, leave and go listen to music or something, then come back, rarely ever watching the entire thing.
I also read very fast but remember things well.

Where can I get a diagnosis? I think the counseling centner at my university might be able to but I'm not sure (I'll be calling them monday) but if they can't who can I turn to?

Can anyone here help me? Advice or relate/ Anything please!
