**TLDR at the bottom. I'm not a total asshole.**

I'm an 18 year old college student with autism/asd. It's not too severe, and I'm able to bumble and stumble through my day normally. One thing that sort of sets me off, though, is isolated loud noises. Ambient noise like a crowded mall or heavy traffic is fine, but things like a baby screaming or a dog barking put me on edge.

At the beginning of the year I tried living on-campus, but the lack of privacy and random noise ultimately drove me back home. Things are better here, but they're not great. Moreover, they're beginning to unravel a bit. 

We have two dogs, used to have three. They have their own little yard to do their business in before being let inside. Ever since the second one died, it seems like the third dog has learned to be as loud and obnoxious as possible to be let back inside.

We also have a wonderful grandmother who lives with us. She, of course, is becoming a bit senile with age. But she's not meek, she's a strong fighting mfer at heart. Unfortunately this means that when she misplaces something, she gets paranoid and shouts at people who she believes "took it".

And in the spring, we'll be fostering a teenager for the first (and supposedly only) time. He will be in court-ordered residential therapy for the next three months before being released to us, probably in March. I was supportive of the rest of the family making this decision, but it's really begun to sink in that this will undoubtedly be rough. 

I try, and mostly succeed, at bottling up my agitation over small things like these, since I'd like to think I'm a well behaved son. But I already have so many other things I bottle up, because I'm too afraid and guilty to bother other people with it. And it gets damaging. I resent myself for not being able to take it easily, but that's the way it is.

On an entirely different storyline, my parents decided a while ago that they would get me an apartment close to school for my sophomore year. I'm currently commuting 45 minutes each way. Of course, I'm incredibly grateful for this, and I'm sure they're getting a kick out of me looking up all these properties relentlessly (it's something I've always been fixated on, some aspies do trains, others do real estate). But I'd really like to move over spring break in March instead of in June or July like originally planned. 

It just makes more sense - I'd be out as the foster kid moves in, it would be during a semester break, and I'd have a 10 minute drive. They'd have more room for the foster kid, and we'd all be less stressed. But I can't help but feel selfish for even asking. It's not entirely about the money; they make enough in a day to pay the rent, and they got a refund for the dorm this semester. I'd be willing to help them pay it regardless. But I feel ungrateful, and I hate hurting other people. 

So am I a spoiled ungrateful asshole that's trying to take more than he's been given, or am I being reasonable in asking?

*TLDR: Autistic college student commuting long way from home. Home is a bit stressful and is only going to get worse as time goes on, and I'm not sure if I'll be able to take it. Parents getting me an apartment this summer, but I want to ask them to make it March for various reasons.*
