Am I being unreasonable?

So my son is now 6 months old and I've been having to raise him majority by myself while his father is "present". Fast forward I'm pregnant again, I'm feeling like I'm slipping into post partum, I feel like my child's father isn't listening to me, and now I have to deal with his brother staying in my house because he has no where to go. I have a bill I have to pay before December and his brother is not helping. He's lazy and disrespectful, my father's child doesn't have a job, and I've been trying to get one for weeks. I'm literally having to do surveys just so I can get by this month and hopefully get a job. At this point I want to kick both of them out and stay and struggle alone by myself. I have to ask them to clean for me or my house will stay dirty. And they are trying to make me feel like I'm being unreasonable and I'm crazy. Please let me know if I am ladies.
