*vent* I have no one else...

So, to start off. I live with my mom, disabled 37 year old brother, 2 year old son, my husband, and am 6 months pregnant. My husband has a job, he brings in around $1400/mo. A 2 bedroom in California is around $600-$700/mo. We live with them, because we honestly can't move out right now. We can't afford rent, pg&e, water/sewer, and garbage on top of all else. My brother is a drug addict, pills. He is rude to me, and my husband. My son bonked his head tonight and my brother has non-stop been messing with his head since. We bought a new back brush for the shower, and my brother used it to scratch his nasty back (he also hasn't showered in a year, and my mom gets paid IHSS to care for him). He pays her $400/mo on top of what she gets to care for him and what she gets from working. Yet, she never has money for bills. She always tells me "I'm so stressed out!! Bills, your brother, and work". I told her to tell him to move, and she refuses. I'm stuck here in this mess, I have no one to watch my kids so I can work too. (This is all over the place sorry) I feel so selfish bringing this baby into this mess, and my depression is very bad now. I'm actually starting to think of things, I don't want to! I don't want rude comments, please? I just need to talk.. or something! I don't know.
