Need advice, my grandma calls me an alcoholic :(

I only drink with my friends on their bdays, every other time is when my grandma’s drinking and offers to let me drink too.

To preface this, I went through my teenage years largely alone and working through mental illness’ alone, figured it out for the most part and im doing very well mentally now. I used to drink a shit ton with my friends during my teenage years & now I really only drink when my friends have bdays at bars & when my grandparents are drinking and playing games (cards or darts) and by the end of the night my grandma ALWAYS without a doubt, calls me an alcoholic.

It makes me feel like shit because alcoholism runs in my family and she’s 100% projecting the issues of my family members onto me because I choose to drink a bit more throughout the night after they go to sleep (because I don’t sleep until 3-4am and I crack myself up when I’m alone, therefore I have more unbridled fun) and it just really makes me feel like absolute crap when she says it especially since I’ve done so much work to get through hereditary mental illness. I’m thinking of turning down her invitations to drink with them because even if I start drinking after her and drink less than her by volume, she’ll still call me an alcoholic even if she’s more fucked up than I am.

Just really makes me feel like absolute shit for even accepting joining in game night. I’m really confused about it and I don’t understand it especially because she ends up getting drunk quicker than me, yet still says that nearly every single time I join in.
