How do I find closure when a girl may not have been honest with me?

had been friends with this girl , mainly see her at her work ( a store ) but also saw her at other places in our home area. at the end of summer i was under the impression she was leaving or taking a break from her job and going to school. but when i talked to her she said she wasn't doing that. however the last time i saw her was Thursday before labour day weekend and she doesn't seem to be at that store anymore

so now left thinking she was not honest with me for some unknown reason and not able to find closure , at least if i knew she was somewhere else doing school i would not have to worry about seeing her in our home area or at that store. and it be easier to put this to rest but now i'm left clueless and without any answers.

its also possible she found another job or went on a trip somewhere would explain her absense , i haven't asked anyone there about her , they were mostly annoyed i went in there so much to see her

she was not at her job on Friday night normally she'd be there so obviously she does not work there now , she is somewhere else but i don't know where , a mystery for the time being so perhaps i can find some closure in the fact she isn't there anymore and at least that provides some answers maybe

this morning i cancelled the instagram request made several months ago to follow her page she never accepted or rejected it , infact never even mentioned it when i saw her inperson. also have still not seen her since sep3rd and have no idea of her whereabouts or if she is even still here or not
