Backstory:
So my brother moved out many years ago, got engaged and broke up and then got engaged to someone else, had two kids and got married.
My other brother moved out when he was turned 18 to move in with his then-girlfriend-now-wife, brought a house, got married and had two boys.
I live at home because I'm in a job that doesn't pay enough for me to be able to move out yet and be financially stable.
The problem:
The second brother always calls before he comes around to ask if it's okay because he doesn't want to be a burden. Comes around once a month, I go over an see them as well when it's okay.
Brother No.1. comes around unannounced every week. New sister-in-law comes around at least twice a week unannounced and stays for the entire day. They ask for us to babysit with about 1 hours notice (sometimes less) and expect us to be prepared for them to visit and he was like this with fiancee No.1.
I might be a little biased because Sister-in-law No.2. is my best friend and we do a lot together but she doesn't come around with brother No.2. all the time so it doesn't really affect the situation.
Am I being unreasonable by wanting them to at least let us know when they are planning at coming around?
Side note: I'm struggling with my mental health atm and sometimes just like to be left alone to deal with it and just sit and cry. Their intrusion doesn't help because I then have to put on a happy face to play with my Nephew even when I feel like the world is upside down.
