Im overreacting right?

I know i likely am, and i genuinely dont think he's interested or anything, and even if he was it would be illegal, but I've developed a big crush on the IT guy at college (he does exams aswell) . I've been there part time since last September (although I've been doing online courses before) at night class and now daytime for one day. My room at night class was on the same corridor as his office, and actually even when i first met him/seen him then i teased him about the last time i did an exam cos he took forever to get the password right 😂😂i actually thought he was a bit odd, bit of a dork at first, like he isn't even remotely attractive but still there seems to be something for me to be attracted to him, which is why im struggling with this/being around him. We spent a lot of time on our own organizing my exam and i need a specific chair for my health (back/tinnitus) and so i would have ventured into his room a lot, he never cared or said i wasn't allowed (im not allowed there in the other campus) there was an actual pinpoint of where it started i guess i seen him in a different light, im sure he was just doing his job but he told me something about my daytime course from his diary that he shouldn't have, gave me his chair for my exam to sit on and just generally been nice to me even though most people are sick of me😂😂

Anyway it was the last night of the course (2 days before my exam) and i was stood near the doorway of the room and there's a little bit of the room that has another door inbetween (there's a printer) and of course i only turned my head for a split second as he's walking past (and no, didn't even know he was there) u can guess it, im convinced there was an eye contact of some sort😂😂 and yet i know deep down it likely wasn't. My teacher pushed me to go see him regarding my exam and it actually felt so awkward and later im literally staring at him and getting distracted 😂😂

More on the update

So my exam was fine i was worried i would give the game away, i failed it. I was so peeved after cos he messed up my retake exam so i gotta do it the day before with the others in my daytime course (they do the core excel, i do the expert) but despite this he still made me smile

So he said on the last night of the course he wouldn't be in the following Monday, but here he says he will be "to help the others" i later found out he didn't come in, i wasn't inWe got moved over to the other campus on Monday we didn't speak, Im having my lunch when he came down & he's infront of me with someone else but hadn't seen me at this point, a little later he's facing me its 😭😂 when he's going out the door he turns his head in my direction

So he was off since feb as his mum died, he was back on Monday but not in my campus so i haven't seen him yet. I still have to do my exam so i spoke to him on the phone, (when i say spoke, i typed to him as i just had an op on my teeth so couldn't actually speak at that point) he's sorted me out for next Thursday which was ideal and i said we are doing presentations on Monday and he said he might come in and watch (i didn't ask if he wanted to come)

He came across shy on the phone and even at the end i literally had to end the conversation 😂 even my mum thought it was weird. Hopefully i see him twice next week and see how things are
