Ok as for your mom the things she’s signing you up for are probably just to keep you active as for the rest seriously try and talk to her, if it doesn’t work then seriously just be colder toward her. Unless you get slapped. Then I really don’t know what to do. As for the pick me girl, you walk up to her and tell her that she is actually being downright annoying and rude
Like if someone says they’re sad console them not “mee too” also if someone says they’re ugly say theyre Not, don’t call them ugly while calling yourself ugly as well then say that’s why you’re besties.
