Just a rant and need an opinion

Ariel
I'm just ranting blowing off stem before I either start crying or something. 
I just feel used by my family. Maybe it's just because I'm pregnant or something. Just seems I'm the only one who takes care of my moms house while both my siblings Hide in their rooms and don't come out unless they need something. My own sister even said that she stays back in her room so she can't be made to do anything. My siblings aren't the nicest to me. I get blamed for everything. Either me or my son or my cat. 
Anymore I feel as if I'm nothing but a servent and have to jump when they call. Hell at family get functions I'm not spoken to and ingnored. I basically give up my pay check to my parents while my sister buys new clothes every week. I don't make much and I'm trying to save its hard when it seems like you pay for almost everything. And left only about $30 for my son and his needs. Honestly I feel as if I'm not welcome in family events. I love to fish with my dad but no one will ask me. I fell forgotten and just that I don't matter.
