and I'm even more worried that I'm self-diagnosing. 

Last Saturday, I was given ritalin at a party (similar drug in terms of official treatment to Adderall). I hadn't been drinking that night, and I was pretty alert otherwise. I took a pill, and the effects kicked in about half an hour later.

It felt like everything that ever frustrated me about the way I thought disappeared. I've always felt that I have a lot of mental clutter going on, and found it hard to focus on projects for long spans of time, no matter how much I tried. I can work in bursts, but not in the long-term. With this, however, it was like all the knowledge I had suddenly got in line and instead of my mind feeling like a tornado had torn through it, it was like a perfectly ordered library. I've been writing notes about a novel project for the better part of three years now, but every time I went to actually sitting down to write it properly, everything disappeared. All those ideas were still in my head, I just couldn't put them in order or pin them down. On ritalin, it was as though I didn't have to beat my mind into submission. I ended up writing a plot outline for six hours solid, and looking over those notes now, everything makes pretty great sense. 

I've wondered for a while if I have some kind of mental issue. Several close family members have commented that as a child, they wondered if I was mildly autistic. My mother, however, denied there was anything wrong, saying I was just trying to find something wrong with myself. 

On several AHD/ADD support sites on the internet, there are initial self-reporting questionnaires available as a starting point. Even my conservative responses to these questionnaires place me firmly in the region of being "likely ADHD". I'm worried, however, that if I go to a doctor, they will think that I just want to get my hands on medication like ritalin. I'm a student at university, and I imagine it's fairly common for people to try to get a prescription for easier studying. But I can't shake the feeling that how I was functioning on ritalin was how I'm meant to be.
<bot>: Took ritalin, could think more clearly than I ever have, want to go to the doctor but unsure if it's a good idea/whether they'll believe me.
