My mom

So I’ve been having this really bad headache for like half of the whole day and I have it still and it’s currently 12:45AM my time, my mom can back from this thing she went to with my stepdad and I told her and all she can say is “I don’t know what you want me to do with it.” And the thing is with her she would rush her self or make a doctors appointment if something was wrong with her but she never does the same with me and my older sister. My sister is like my mom because my real mom doesn’t even take care of me like how she should. It’s so sad that my 16 year old sister has to take care and love me because my own mother doesn’t act like I’m alive or like a ghost, everyday I try talking to her but she’ll sit on her phone and ignore me and act like I’m listening I’m so tired of it. Then when she goes and talks and says she ‘loves’ my older sister she doesn’t come in my room and says anything to me. I’m so sick and tired of feeling like I’m nobody. I’m so done sorry for the rant.
