I told my sister that im agnostic

me and my sister are close, she’s muslim and yesterday i took her for a drive because she was feeling down and we talked and talked and I didn’t try to go through any religious opinions but i always hinted that im having a hard time believing in some “stuff” in islam, and throughout the convo i just said “i think u deserve to know, im agnostic” and she didn’t backfire or give a noticeable reaction, i assume she low key knew and ngl im worried it might effect our relationship later or at least she’s gonna see me differently, anyone with a similar story what’s the after math?
