Is this Nothing or Something?

I'm a student of neuroscience and loving it, but the more I'm learning and meeting more people the more I'm noticing some things about myself that aren't as normal as I thought. I don't think it has affected me in a severe way, but I wonder if things might be easier if I sought treatment.
For starters I have a reaction to particularly colorful or flashy games. It seems to be mostly a large increase in mucus production, but it must be higher up because my eye notice it the most. They also water and my vision seems to get worse (but that could just be all the gunk in them.) The worst case of this occured when I was younger and at my grandmother's playing Dr. Mario (pretty colorful) and my eyes were just caked and tears were pouring down my face. I wasn't crying but it still made everyone nervous.. not that it stopped me from playing. Those have been much more mild and less common since, but there's definitely something going on with some video games still.
Another small thing is that I have a tic anytime I have one of those chills. The chills aren't uncommon but they're always accompanied by a tic where my head will make a quick rotation to the left. the motion is like my chin is trying to reach my left ear's position. Pretty much always the same, it may have gone to the right but I can't be certain. I think I just stretch that way after. I can prevent this if I notice other people around, but it feels uncomfortable when I do.
Those things don't bother me, but I feel like I have trouble following my own thoughts sometimes and I've always been known to have some trouble communicating or being a bit awkward among others and those are the things I would like to see some change in if possible. Focus and memory are becoming more difficult as I'm having to push my brain much harder now than ever before with my education.
There are a couple events that could have had light influence on cognitive ability.  I had meningitis (viral, thank god) when I was about 10 and I had a traumatic event involving suffocation when I was 8. I don't know how long I was out for but it definitely didn't do any favors for my brain. I have had a known seizure once when I was maybe 12 and it was just and absence seizure followed by a panic attack, but that could very well have been more of a puberty thing.
All this could be nothing, and maybe all of the current problems are stress related, but if there's something I should look into to maybe help my poor head I'd really like to know.  I really appreciate you reading this too. Thanks and I hope to hear from somebody soon.
