AIBU for being depressed and stressed since my MIL moved in with us?

[sarusingh]

Recently my FIL passed away (RIP) and my MIL has moved in with us from India. I have been married for 15 years and have 5 years old twins and I feel like my life has just changed all of a sudden. I know I should be more accommodating and accepting of my new living arrangement, but I've been really depressed and stressed, thinking about how to make things work, given that we both work full time and are constantly struggling and trying our best to be good parents.
Am I being unreasonable for feeling so down and wishing that I had my old life where I had more space and freedom in my own house?

@LaurieMarlow - india doesn’t have a welfare state. So if OP’s DH’s parents have sold all of their assets to send him to the UK (which is likely) then he owes reciperocle care. He does. Not her.

Any choices they made for their children do not bind their children to debts for life.
Bottom line is the moment their children left their country and their culture it was their responsibility to make a plan B. This hasn't happened. MIL was not old and widowed when her children emigrated and married outside of their culture.
That was the moment her and FIL should have made plans for their retirement as they were the ones to stay in India alone. With no support.
Their plan was to move to a country where they had contributed nothing and as such receive no benefits or support and become a financial, emotional and physical burden to their children.

They never gave any thought to consulting their children's partners. Never looked into immigration or conceal assistance.
Indian culture might work in India. But this isn't India. And as such she needs to seriously get out of her fixed mindset.

If she’s moved in with you, she should be helping out, don’t cultures where multigenerational households are common entail grandparents helping out with cooking/cleaning? And if she’s too infirm for that it may not be safe for her to live with you. My dad’s older than her, and goes out running, works as a dog walker and shelf stacker. With no other health concerns, 70 is too young to decide you’re someone else’s problem.
