It might pass. How old is she, how old are you? Just saying that moms can be surprised and disapproving at first, but mellow out over time. Like, they will totally screech, “I didn’t raise you to be so __________________!” But eventually they’ll remember you’re a good person.
Like, my own mom used to be homophobic. Then my sister came out as lesbian, and mom kicked and screamed and eventually pulled a 180 and became totally supportive. She also used to be hyper-anti-drug, until I was straight with her about how (non-prescription) weed helped my anxiety and quieted down my racing/intrusive thoughts (which she also has problems with). She spent a couple years bitching at me something fierce about being a heinous druggie (keeping in mind I was employed, financially-independent, and very happy with my boyfriend at the time). So, eventually, she resolved her cognitive dissonance–weed didn’t turn me into a worthless/lazy/unemployed/undateable piece of shit. Maybe it wasn’t all that bad! She became much more lax wrt my drug use, and eventually even tried it herself. She even asked if I might be able to procure some for her at one point (I couldn’t, but it’s the thought that counts).
Moms can be cool. Only time will tell.
