I hate my family

So Lately my nana has been getting stricter like she’ll ground me for a week just if i forget to not do a pan in the kitchen and she only grounds me from my boyfriend and she started getting stricter when i started dating him (3 1/2 months ago) like Friday she went threw my room and found a condom wrapper but we don’t even use condoms anymore, and she found pods all over and now she’s being a bitch and not letting me do anything or see him for a while. I don’t think that she should ground me from him bc we don’t even go to the same school so i don’t get to see him a lot anyways accept out of school. Like idk anymore
