<human>: Can you provide a brief rundown of the text in within 3 sentences?

Ahoy, Reddit.

I need advice for something that transpired within a matter of two days. But first, a little backstory.

My brother and I have never had a very positive relationship. When I was younger, we were never close, nor did he show any kind of care towards me and our other younger siblings. There were a few times he even physically assaulted me so growing up, I felt mostly threatened by him.

Fast-forward to present day. My brother has never held a steady nor full-time job and he's usually asking for handouts from my mom and dad (separated). My mom doesn't work due to her health and my dad has to provide for my step-family of 7.

A couple of months ago, my brother got laid off from his job. He can no longer afford the rent to pay for his place (with roommates) and gets kicked out. He calls my mom on August 1st and she goes to pick him up and moves his stuff into our place.

Now, our apartment is a modest 1 bedroom. I let my mom have the bedroom and I sleep in a futon in the living room. With my brother there, it's pretty tight, not to mention mentally uncomfortable. I'm finishing up my final semester of college complete with 7 courses, working part-time, searching for internships for next spring, studying my ass off for the GRE, you get the deal. 

For the last two years, in accordance with my International Relations degree, I have been abroad in Japan, Egypt, and Palestine, respectively. I've Skyped with my mom regularly and not once did she mention my brother was moving in during the past month.

I've had a serious talk with my mom about this huge issue. I told her many times in a one-to-one conversation that my brother cannot stay here. He's a 30 year old man, for fuck's sake. I don't know how to get him to move out and let me have my space that is rightfully mine.
<bot>: I came home after 2 years of semesters abroad to find that my mom let my piece of shit brother move into my space in our apartment. I need him to move out STAT.
