Does anyone else know what to do?

I have a soon to be three year old daughter. As of late it seems like my family can't stand her at all. Like they do what ever they can to not be around her and be mean. Have zero clue to why or what is even going on.

When I ask why, I get a huge attitude from my mother and told I am just sealing attention and looking for drama.

Plans for the holidays were changed without me knowing. My sister who is a huge liar, steals from my mom and uses her for money is being allowed over with her girlfriend that does the same.

I was informed we are not apart of thanksgiving this year at all. If my boyfriend is working then it will just be the little one and me. I am hurt over how they are acting and treating us.

I have no idea what to even say anymore to them or about things.
