OP....my folks always had a saying...."my house, my rules". While I was living there, I got to jump through their hoops.
It sounds like you are the only one not working, which sets you as the default to take some of the household work off your mom. And as it is her house, I think she has the right to some privacy to herself.
I'm sorry that you have issues that make it difficult to move quickly in the morning, but NOW is the time to try to deal with these. Any employer.....or professor, is not going to be sympathetic to the fact that you won't be able to get to a job or class by 9 am. If you are sleeping in past 10 or 11 in the morning, I can see how your mom might start to resent this and it is not a good habit to acquire on a regular basis.
The onus is on you to try to make your mom's life as easy as possible, since she is not only footing your living expenses, she is footing them of your b/f. IMO, that is incredibly generous of her.
About your b/f's mother, that is his problem to deal with. Taking money from a parent gives them rights to ask. So if your b/f does not like this, then it is his choice not to accept the money from his mom.
