They probably will not care if you "publish" in an undergrad "journal." OP, you have a pub, you hate research, you got what you came for. Unless you like the torture of doing something you hate, you need no more of this suffering. Go high on a mountain, and yell at the top of your lungs "LET MY PEOPLE GO," be at peace, and go home a new man, enlightened and free of the burden that once was research.
LOL, indeed. That's the attitude. If you hate research, and got your pub...you can get out and spend your time on something meaningful. ;D . Unless you want to come out as a real research beast, the benefit of anything after the first publication is small.
Funny though, how people are cool with bashing research, but when it comes to "enough volunteering" you get whipped for "doing it for the wrong reason." I did a lot of research, and I did it because I enjoyed it. And the pubs came. And I chased the pubs.
OP, as you mentioned, you are more suited for volunteering. Pursue your calling.
...OK, that was a little sarcastic. Go back to clinical studies/observation, and if you want, make notes, observations, analysis, etc. whatever. Maybe you can make something out of it and publish it in a real journal. If not, publish it in your undergrad journal....keep a flow going. Start your own blog in the school paper, whatever. You'll be able to talk about it much better than a pub you stumbled through and can hardly feign interest it, and you'll show dedication to the "down to earth stuff," which is what some schools look for anyway.
It will be low yield for you past this point to force yourself to do research.
To conclude, you have done "enough." A pub is already more than most undergrads.
