i think i took wayyyy too much lamotragine thinking it was another med and im freaking out

not sure if this is the right place or if i'm going to sound ridiculous but... i'm on 100mg lamotragine daily after tapering down for a while. i take about 60mg adderall IR (40ish when i wake up and 20 around noon for a boost). so for the past week or two i've had a UTI that i believe began to become septic. since tuesday i've been on antibiotics that seem to be working, but life noticed i don't have the best memory over the last two weeks.

the last few days, my adderall barely feels like i'm taking it (though i have been on it in different doses 10+ years.) the tablets of adderall and lamotragine are somewhat similar - both a lighter pink/orange color although the adderall is football shaped and lamotrigine is round i typically do not keep these two bottles nearby each other, therefore i don't typically inspect the medication, and because i take the adderall when im barely awake. this morning i noticed i was not feeling anything kick in, and grabbed the same bottle and swallowed another. still nothing. i decided to break a 4th HALF of a 20mg adderall (only 10mg over my daily 60mg adderall dose, but really needed today to be a productive day). i dropped the second half under the couch and when i finally went to grab it, i noticed it looked off. sure enough, i checked, and i believe i had been taking the lamotrigine all morning (so about 3.5x my regular dose OF LAMOTRIGINE within three hours of each other). immediately i went into a state of panic, hoping i hadn't been doing that for days prior and if the lack of adderall's effect was just due to my infection.

so ultimately, i do realize and feel like a complete idiot, and going forward will be MUCH more thorough and cautious with which meds im grabbing and taking - but as for today, is there anything specific i need to be concerned about? i feel completely off and disoriented and i believe the anxiety is only exacerbating it. if anyone has any tips or confirmation that i should be freaking out (or i shouldn't) id love to know so i can take necessary steps from there.

side note, aside from the completely unsettled mental state, i am experiencing some gnarly stomach cramps and temperature fluctuations, which i am not surprised by.

tyia y'all!

edit: i am took a zofran this morning before i realized what ive done which probably was no help, but i am also prescribed xanax and not sure if taking a few of those might help

second edit: i did not take 3.5x my prescribed adderall dose.... it was about 10mg(.5x?) more (prescribed 60mg in three 20mg pills... took half of of a 20 = 10mg. equalling 70mg of adderall when i am prescribed 60mg.) this translates differently when it is not adderall being taken but rather lamotrigine.
