I hate being here this much

As I write this post, I am at my grandmothers place. After loosing my grandfather my grandma has been suffering from some anxiety disorder where she can't stay alone for even 2 hours. Problem is my parents want me to keep her company and I am not a very tolerable person. The house is full of mosquitoes and so hot here I can't sleep at night, the neighbors make such a din and besides her talking a lot she has a lot of visitors everyday and is constantly asking me stuff, which I'm not used to. My aunts away for two weeks and normally stays with my grandma. My mom gets I'm struggling here and says she'll come instead but I dont want to inconvenience her. What I want to know is if its normal to be so annoyed here I'm getting my own kind of anxiety...and how do I deal with this?
