17m, is there any way to deal with limerence?

im pretty sure im limerent about this girl at work and its getting to me mentally. i get uncomfortable speaking about it like this but i have thoughts while going on about my days of what she would think of what im doing or of me subconsciously and i try to snap out of it but it keeps happening. i only started seeing her again at work since last week after months of nothing at all (i switched my availability for my shifts not for her but i was already challenging myself to wake up earlier during the days). I thought i got over it but clearly i didnt and i had this idealized image of her especially during the time i didnt see her and now when i do i feel super awkward and unnatural because of my thoughts.

I actually want to get to know this girl but my mindset is holding me back from letting it happen naturally and i hate that i tend to put people on pedestals and overthink when its really not that deep. Like at work today i felt like i absolutely embarrassed myself at drive thru window (pos broke; not my fault) but i was super slow, messed up orders and made things harder for her on her end & i feel like theres no chance she didnt get the ick or think of me as lesser😭 i feel like my overthinking abt her mightve had to do with it too and i just really REALLY want to stop thinking like this. I want to love myself and live in the present moment not torture myself with things im making up in my own head. as im writing this post im losing sleep because of these thoughts (also i have trouble sleeping in general w adhd and bc of medication) Any advice please thanks
