My fault??

Sooo tonight my parents invited our grandparents over for dinner (ya know day before Easter) welllll my parents got drunk, my stepmom had 2 bottles of wine. My dad was fine, just kinda tipsy. My stepmom was being really nice to me, she actually hugged me and we laughed and talked and it was amazing. But then my grandparents left.

My stepmom remembered that she hadn’t fill Easter eggs for my little bros, so I said I’d do it and my stepbrother said he’d help. So my stepbrother and I were filling the eggs and we were singing silly songs because that’s what teenagers do. My stepmom asked about the milky ways and I tried to explain to her that there was to much candy for the eggs. But to please her we put more than one piece of candy in the eggs(not a problem) but she wanted all the candy gone. So we said we’d do it and my bro and I were messing around and joking about the eggs. My stepmom got upset and started helping saying “I didn’t want to do this” and she got all hurt and my dad tried to talk to her and tell her that she needed sleep, but she stormed out of the house. After a couple minutes my dad went out to talk to her, my stepbrother and I finished and hid the eggs.

I’m in bed rn, I only heard the door open once and dishes are being cleaned so I’m 99% sure it’s my stepmom. We are all probably not going to the sunrise service at my church tomorrow. This sucks but was is my fault?? I just feel horrible.
